Chemical Structure
Description
CATO supplies Tris(4-chlorophenyl)phosphine (CAS 1159-54-2), a certified reference material (molecular formula C18H30Cl3P, MW 383.76 g/mol) for analytical method development and quality control.
Tris(4-chlorophenyl)phosphine (C18H30Cl3P) contains organophosphorus functionality, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 Tris(4-chlorophenyl)phosphine 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.
