Chemical Structure
Description
Bis(2,2,2-trichloroethyl)phosphoryl chloride (CAS 17672-53-6), molecular formula C4H4Cl7O3P and molecular weight 379.22 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Bis(2,2,2-trichloroethyl)phosphoryl chloride (C4H4Cl7O3P) is characterized by a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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 Bis(2,2,2-trichloroethyl)phosphoryl 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.
