Chemical Structure
Description
The occurrence of S-(3,5-di-tert-butyl-4-hydroxyphenyl) 3,5-di-tert-butyl-4-hydroxybenzenesulfonothioate is closely related to a steroid core, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
S-(3,5-di-tert-butyl-4-hydroxyphenyl) 3,5-di-tert-butyl-4-hydroxybenzenesulfonothioate (CAS 66729-87-1), molecular formula C28H42O4S2 and molecular weight 506.76 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, a sulfone group, a hydroxyl group, an ether linkage, S-(3,5-di-tert-butyl-4-hydroxyphenyl) 3,5-di-tert-butyl-4-hydroxybenzenesulfonothioate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 506.76 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 S-(3,5-di-tert-butyl-4-hydroxyphenyl) 3,5-di-tert-butyl-4-hydroxybenzenesulfonothioate 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.
