Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 178.98 g/mol gives Dichlorophenylphosphine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Dichlorophenylphosphine (CAS 644-97-3), molecular formula C6H5Cl2P and molecular weight 178.98 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Dichlorophenylphosphine (C6H5Cl2P) is characterized by organophosphorus functionality, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 Dichlorophenylphosphine 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.
