Chemical Structure
Description
Methyl 3-bromo-5-(((trifluoromethyl)sulfonyl)oxy)-4-(trimethylsilyl)benzoate (CAS 1242069-32-4), molecular formula C12H14BrF3O5SSi and molecular weight 435.29 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Methyl 3-bromo-5-(((trifluoromethyl)sulfonyl)oxy)-4-(trimethylsilyl)benzoate (C12H14BrF3O5SSi) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
