Chemical Structure
Description
The occurrence of (Disulfanediylbis(4,1-phenylene))dimethanol is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (Disulfanediylbis(4,1-phenylene))dimethanol (CAS 7748-20-1), a certified reference material (molecular formula C14H14O2S2, MW 278.39 g/mol) for analytical method development and quality control.
(Disulfanediylbis(4,1-phenylene))dimethanol (C14H14O2S2) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 (Disulfanediylbis(4,1-phenylene))dimethanol 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.
