Diphenyl pentylphosphonate CAS 21645-07-8

Description

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

CATO supplies Diphenyl pentylphosphonate (CAS 21645-07-8), a certified reference material (molecular formula C17H21O3P, MW 304.32 g/mol) for analytical method development and quality control.

Owing to a steroid core, a phosphonate group, a hydroxyl group, an ether linkage, Diphenyl pentylphosphonate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 304.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

CATO manufactures Diphenyl pentylphosphonate 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.
