Chemical Structure
Description
Benzhydryltriphenylphosphonium chloride (CAS 1530-43-4) is a high-purity analytical reference standard with the molecular formula C31H26PCl and a molecular weight of 464.97 g/mol.
Owing to organophosphorus functionality, chlorine substitution, a polycyclic aromatic system, Benzhydryltriphenylphosphonium chloride is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 464.97 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures Benzhydryltriphenylphosphonium chloride 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.
