1,2-Bis(dichlorophosphino)benzene CAS 82495-67-8 chemical structure

Description

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 supplies 1,2-Bis(dichlorophosphino)benzene (CAS 82495-67-8), a certified reference material (molecular formula C6H4Cl4P2, MW 279.86 g/mol) for analytical method development and quality control.

1,2-Bis(dichlorophosphino)benzene (C6H4Cl4P2) contains organophosphorus functionality, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

CATO manufactures 1,2-Bis(dichlorophosphino)benzene 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.
