Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Trifluoro-methanesulfonic acid dimethyl(1-phenylethyl)silyl ester (CAS 164590-76-5), a certified reference material (molecular formula C11H15F3O3SSi, MW 312.38 g/mol) for analytical method development and quality control.
Structurally, Trifluoro-methanesulfonic acid dimethyl(1-phenylethyl)silyl ester (C11H15F3O3SSi) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 312.38 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures Trifluoro-methanesulfonic acid dimethyl(1-phenylethyl)silyl ester under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
