Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-Methoxy-2-(4-methoxyphenyl)-3-(p-tolylthio)benzo[b]thiophene 1-oxide.
6-Methoxy-2-(4-methoxyphenyl)-3-(p-tolylthio)benzo[b]thiophene 1-oxide (CAS 477762-69-9), molecular formula C23H20O3S2 and molecular weight 408.53 g/mol, is a CATO reference standard with documented purity and traceability.
6-Methoxy-2-(4-methoxyphenyl)-3-(p-tolylthio)benzo[b]thiophene 1-oxide (C23H20O3S2) contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 6-Methoxy-2-(4-methoxyphenyl)-3-(p-tolylthio)benzo[b]thiophene 1-oxide 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.
