Description
CATO manufactures (Disulfanediylbis(2,1-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.
CATO supplies (Disulfanediylbis(2,1-phenylene))dimethanol (CAS 35190-71-7), a certified reference material (molecular formula C14H14O2S2, MW 278.39 g/mol) for analytical method development and quality control.
(Disulfanediylbis(2,1-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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
