Chemical Structure
Description
CATO supplies 4,4'-Dichloro diphenyl sulfide (CAS 5181-10-2), a certified reference material (molecular formula C12H8Cl2S, MW 255.16 g/mol) for analytical method development and quality control.
The molecular framework of 4,4'-Dichloro diphenyl sulfide (C12H8Cl2S) is characterized by sulfur-containing functionality, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 4,4'-Dichloro diphenyl sulfide 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.
