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 2-((4-Bromophenyl)thio)-3-((4-chlorophenyl)sulfonyl)-4,6-dimethylpyridine.
2-((4-Bromophenyl)thio)-3-((4-chlorophenyl)sulfonyl)-4,6-dimethylpyridine (CAS 478262-70-3), molecular formula C19H15BrClNO2S2 and molecular weight 468.81 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, chlorine/bromine substitution, 2-((4-Bromophenyl)thio)-3-((4-chlorophenyl)sulfonyl)-4,6-dimethylpyridine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 468.81 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2-((4-Bromophenyl)thio)-3-((4-chlorophenyl)sulfonyl)-4,6-dimethylpyridine 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.
