Chemical Structure
Description
The occurrence of 3-(Benzenesulfonyl)-4-methyl-2-[(4-methylphenyl)sulfanyl]-6-phenylpyridine is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-(Benzenesulfonyl)-4-methyl-2-[(4-methylphenyl)sulfanyl]-6-phenylpyridine (CAS 343372-77-0), molecular formula C25H21NO2S2 and molecular weight 431.57 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 3-(Benzenesulfonyl)-4-methyl-2-[(4-methylphenyl)sulfanyl]-6-phenylpyridine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 431.57 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 3-(Benzenesulfonyl)-4-methyl-2-[(4-methylphenyl)sulfanyl]-6-phenylpyridine 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.
