4,4'-Sulfinyldiphenol CAS 1774-34-1

Description

Compared with other compounds in its class, the molecular weight of 234.27 g/mol gives 4,4'-Sulfinyldiphenol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4,4'-Sulfinyldiphenol (CAS 1774-34-1), molecular formula C12H10O3S and molecular weight 234.27 g/mol, is a CATO reference standard with documented purity and traceability.

4,4'-Sulfinyldiphenol (C12H10O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, 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.

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 4,4'-Sulfinyldiphenol 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.
