Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (3a<I>R</I>,8a<I>R</I>)-4,4,8,8-tetrakis(3,5-di-tert-butylphenyl)-2,2-di Ethyl-6-phenyltetrahydro-[1,3]dioxa[4,5-<I>e</I>][1,3,2]dioxaphosphorane.

(3a<I>R</I>,8a<I>R</I>)-4,4,8,8-tetrakis(3,5-di-tert-butylphenyl)-2,2-di Ethyl-6-phenyltetrahydro-[1,3]dioxa[4,5-<I>e</I>][1,3,2]dioxaphosphorane (CAS 1241684-27-4), molecular formula C71H131O4P and molecular weight 1079.77 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (3a<I>R</I>,8a<I>R</I>)-4,4,8,8-tetrakis(3,5-di-tert-butylphenyl)-2,2-di Ethyl-6-phenyltetrahydro-[1,3]dioxa[4,5-<I>e</I>][1,3,2]dioxaphosphorane (C71H131O4P) is characterized by a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 (3a<I>R</I>,8a<I>R</I>)-4,4,8,8-tetrakis(3,5-di-tert-butylphenyl)-2,2-di Ethyl-6-phenyltetrahydro-[1,3]dioxa[4,5-<I>e</I>][1,3,2]dioxaphosphorane 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.
