Chemical Structure
Description
The occurrence of 2-chlorophenyl dichloro(sulfanylidene)phosphinite is closely related to sulfur-containing functionality, organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-chlorophenyl dichloro(sulfanylidene)phosphinite (CAS 68591-34-4), a certified reference material (molecular formula C6H4Cl3OPS, MW 261.49 g/mol) for analytical method development and quality control.
Structurally, 2-chlorophenyl dichloro(sulfanylidene)phosphinite (C6H4Cl3OPS) contains sulfur-containing functionality, organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 261.49 g/mol, it falls into the medium-molecular-weight range. 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).
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 2-chlorophenyl dichloro(sulfanylidene)phosphinite 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.
