Chemical Structure

Phenyl phenylphosphoramidochloridate CAS 51766-21-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Phenyl phenylphosphoramidochloridate.

CATO supplies Phenyl phenylphosphoramidochloridate (CAS 51766-21-3), a certified reference material (molecular formula C12H11ClNO2P, MW 267.65 g/mol) for analytical method development and quality control.

Phenyl phenylphosphoramidochloridate (C12H11ClNO2P) contains a nitrogen-containing heterocyclic scaffold, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), Phenyl phenylphosphoramidochloridate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
