2-(Diphenylphosphino)benzenethiol CAS 119327-17-2 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

2-(Diphenylphosphino)benzenethiol (CAS 119327-17-2), molecular formula C18H15PS and molecular weight 294.35 g/mol, is a CATO reference standard with documented purity and traceability.

2-(Diphenylphosphino)benzenethiol (C18H15PS) contains sulfur-containing functionality, organophosphorus functionality, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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).

CATO manufactures 2-(Diphenylphosphino)benzenethiol 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.
