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 N-{4-[(4-bromophenyl)sulfanyl]phenyl}-2-chloro-4-methanesulfonylbenzamide.
N-{4-[(4-bromophenyl)sulfanyl]phenyl}-2-chloro-4-methanesulfonylbenzamide (CAS 339031-33-3), molecular formula C20H15BrClNO3S2 and molecular weight 496.83 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-{4-[(4-bromophenyl)sulfanyl]phenyl}-2-chloro-4-methanesulfonylbenzamide (C20H15BrClNO3S2) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
