Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including [3-Fluoro-(4-trifluoromethoxy)phenyl]-methanesulfonyl chloride.
CATO supplies [3-Fluoro-(4-trifluoromethoxy)phenyl]-methanesulfonyl chloride (CAS 1987007-00-0), a certified reference material (molecular formula C8H5ClF4O3S, MW 292.64 g/mol) for analytical method development and quality control.
The molecular framework of [3-Fluoro-(4-trifluoromethoxy)phenyl]-methanesulfonyl chloride (C8H5ClF4O3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
