Gute Chemie Foreword 2|3 Gute Chemie. Welcome to abcr. What do you think of when you hear the expression „Gute Chemie“? Does it make you think of top-quality products or people that understand each other really well? Since we set up our company in 1987, we have consistently attempted to combine both. We offer Gute Chemie in the form of more than 260,000 specialty chemicals that we supply to major pharmaceuticals and chemical companies. And we also provide Gute Chemie in terms of our personal service coupled with an extensive network that links our clients, suppliers and partners all around the world. With this brochure, we would like to invite you to experience all the aspects of Gute Chemie. Dr. Jan Schuricht
Commercial Organofunctional Silanes for Diagnostics and Separation Sciences. Organofunctional silanes are widely used commercially for diagnostics and separation science due to their re- markable versatility. They are hybrid molecules that combine the functionality of a reactive organic group and inorganic functionality into a single molecule. This unique property is used as a molecular bridge to make inorganic materials organically compatible. Organofunctional silanes molecules have two reactive centers, one characterized by at least one hydrolyti- cally stable carbonsilicon bond which allows the intro- duction of non-reactive or reactive organic functionality such as alkyl, aryl, arylalkyl, perfluorophenylalkyl, amino, epoxy, aldehyde, ethylene and anhydride. The other re- active centers of the silicon atom are characterized by hydrolyzable groups, mainly chloro, alkoxy and amine. The hydrolyzable component of organofunctional silanes will hydrolyze readily with water to form silanols and allow silicon to covalently bond to inorganic surfaces through a siloxane bond. In addition to forming covalent siloxane bonds with inor- ganic substrates, the hydrophobic nature of the silicon- carbon bond provides improved resistance at the inter- phase between siloxane bond and substrate to hydrolysis attack under extreme pH conditions. This feature makes stationary phases and the silica support matrix used in liquid chromatography more hydrolytically stable and hence, indreases service life by protecting the silica’s mechanical properties. The organofunc- tional silanes can be tri-functional, di-functional and mono-functional. Typical molecular structure for a tri-functional silane R X (CH ) n 2 Si R R R can an example be for chloro, dimethylamine or methoxy X can an example be for hydrogen, perfluorphenyl, phenyl, amino, oxy or cyano In order to initiate the hydrolysis reaction of organofunc- tional alkoxysilanes to subsequently form covalent silox- ane bonds, a catalyst is generally required; typically a mild acid or base will be sufficient. The most common catalysts are acetic acid and ammonia. Chlorosilanes and aminosilanes are autocatalytic because the hydro- lyzable groups will generate in situ, hydrochloric acid or amine thus creating a reaction medium with an acid catalyst with pH 0-1 or a base catalyst with pH 12-14. The tri-functional silanes, e.g. trimethoxysilanes, hydro- lyze first to form a silanol group and then condense with surface hydroxyl groups to form a hydrolytically stable covalent bond and also crosslink to form a multilayer (silsequioxane) coating. This multilayer is formed at the inorganic interphase and can also diffuse into the a po- rous matrix to create an interpenetrating network with- in the inorganic substrate which, in turn, generates a more hydrolytically stable silica support for liquid chro- matography. The di-functional silanes, e.g. dimethoth- oxysilanes also hydrolyze first to form a silanol group and then condense with surface hydroxyl groups to form hydrolytically stable covalent bonds. The di-func- tional silanes can also form polymeric materials that can adhere to different types of surfaces. Therefore, organo-functional silanes that are di-functional can be used to make bonded phases for liquid chromatography or make siloxane polymers for capillary columns used in gas chromatography. The mono-functional silanes due to their single hydrolyzable reactive group will form a self-assemble-monolayer (SAM) on the inorganic sub- strate thus creating a uniform molecular layer on the inorganic substrate’s surface. This may offer advanta- ges because the film thickness is easily controlled where it is well known that for tri- and di- functional silanes: reproducibly controlling the film thickness can be quite challenging. Typically, mono-functional silanes are used to make bonded phases for analytical applications while due to the higher hydrolytic stability, the di- and tri-functional silanes are more commonly used to make bonded phases for sample prep-scale chromatography, solid phase extraction (SPE) and preparative chromatography
Gute Chemie Commercial Organofunctional Silanes Reagents 2 | 3 for the purification of active pharmaceutical ingredients (API). An important aspect of bonded phases for liquid chromatography is capping (endcapping) of unreacted silanol groups left on the inorganic surfaces after the bonding phase step. These unreacted hydroxyl groups adversely affect performance and are therefore capped with a trimethysilyl group. Hydroxyl and free water scavengers like trimethylchlorosilane and hexamethyl- disilazane are efficient however a customized solution of trimethylchlrosilane and hexamethyldisilazane has a higher reactivity and is more effective than either of the reagents alone. In addition, capping of silanols groups will lead to free flowing particles which may aid in the reproducibility of column pressures of bonded silica packed chromatography columns. Organofunctional silanes with a hydrolyzable dimethylamino group are versatile silylating reagents for capping silanols. Due to its extreme reactivity with hydroxyl groups, dimethyl- aminotrimethylsilane is a highly effective silanol scav- enger. The by-product formed, dimethylamine, can be easily removed during reflux or by applying vacuum. It must be noted that dimethylamino silanes are ex- tremely hydrolytically sensitive, even more reactive than chlorosilanes. They will almost instantaneously react with moisture in the air; water contained in polar solvents, adsorbed on the surfaces of glass bottles and GC vials. When handling these types of products dur- ing analysis, the use of inert gases, silanized GC vials, anhydrous solvents for syringe cleaning and GC column pre-conditioning are highly recommended. In order to facilitate analysis and process handling these products are also offered as a solution in a non-polar solvent. Depending on the analyte, retention time and selectiv- ity, there are numerous organofunctional silanes avail- able for gas and liquid chromatography. A stationary phase is defined by the specific chemical ligands bond- ed to the silica support which in combination with sol- vent and pH, control selectivity and retention time of analytes. The mobile phase is defined by the solvent which contains the analytes. The solvent can be gas as in the case of gas chromatography or non-polar sol- vents for normal phase chromatography (NPC) or polar solvents for reverse-phase chromatography (RPC) and hydrophilic interaction chromatography (HILIC). Gas (GC) and Liquid Chromatography (LC) employ specific modes of separation which are influenced by the polar- ity of the stationary phase. The most common ligands found in commercial station- ary phases are: Alkyl Phases C18 C8 C4 C1 Phenyl Phases Phenyl Phenyl- alkyl Polar embedded Phases Polar Phases Perﬂuor- phenyl- propyl Cyano Amino Hydroxyl In addition, in the field of biochromatography, whole new classes of ligands are being investigated for the analysis and purification of natural compounds that are biologically active. Selectivity and retention time are being optimized based on the affinity of these natural compounds to different ligands. The particular nature of the analyte will determine the choice of organofunctional silane as well as the way in which it bonds to the supporting silica matrix.
