Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Methyl 3-Bromo-4-(methylsulfonyl)benzoate (CAS 182003-84-5) is a high-purity analytical reference standard with the molecular formula C9H9BrO4S and a molecular weight of 293.13 g/mol.
The molecular framework of Methyl 3-Bromo-4-(methylsulfonyl)benzoate (C9H9BrO4S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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).
CATO manufactures Methyl 3-Bromo-4-(methylsulfonyl)benzoate 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.
