Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies 21101-56-4 3,3'-Dihydroxydiphenyl Disulfide 3,3'-Dithiodiphenol B3149 Bis(3-hydroxyphenyl) Disulfide (CAS 21101-56-4), a certified reference material (molecular formula C12H22O2S2, MW 262.43 g/mol) for analytical method development and quality control.

Structurally, 21101-56-4 3,3'-Dihydroxydiphenyl Disulfide 3,3'-Dithiodiphenol B3149 Bis(3-hydroxyphenyl) Disulfide (C12H22O2S2) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 262.43 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

CATO manufactures 21101-56-4 3,3'-Dihydroxydiphenyl Disulfide 3,3'-Dithiodiphenol B3149 Bis(3-hydroxyphenyl) Disulfide 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.
