Mono(2,4-di-tert-butylphenyl)phosphate CAS 18351-37-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Mono(2,4-di-tert-butylphenyl)phosphate.

Mono(2,4-di-tert-butylphenyl)phosphate (CAS 18351-37-6) is a high-purity analytical reference standard with the molecular formula C14H23O4P and a molecular weight of 286.30 g/mol.

Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, Mono(2,4-di-tert-butylphenyl)phosphate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 286.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 Mono(2,4-di-tert-butylphenyl)phosphate 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.
