Chemical Structure

(11aS)-1,2,10,11-Tetramethyl-4,8-bis(t-butyl)-6-[[(2S,5S)-(2,5-diphenyl-1-phospholanyl) methoxy]-dibenzo[d,f][1,3,2]dioxaphosphepin] CAS 1373349-83-7 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 (11aS)-1,2,10,11-Tetramethyl-4,8-bis(t-butyl)-6-[[(2S,5S)-(2,5-diphenyl-1-phospholanyl) methoxy]-dibenzo[d,f][1,3,2]dioxaphosphepin].

(11aS)-1,2,10,11-Tetramethyl-4,8-bis(t-butyl)-6-[[(2S,5S)-(2,5-diphenyl-1-phospholanyl) methoxy]-dibenzo[d,f][1,3,2]dioxaphosphepin] (CAS 1373349-83-7) is a high-purity analytical reference standard with the molecular formula C41H50O3P2 and a molecular weight of 652.78 g/mol.

The molecular framework of (11aS)-1,2,10,11-Tetramethyl-4,8-bis(t-butyl)-6-[[(2S,5S)-(2,5-diphenyl-1-phospholanyl) methoxy]-dibenzo[d,f][1,3,2]dioxaphosphepin] (C41H50O3P2) is characterized by a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic 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 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 (11aS)-1,2,10,11-Tetramethyl-4,8-bis(t-butyl)-6-[[(2S,5S)-(2,5-diphenyl-1-phospholanyl) methoxy]-dibenzo[d,f][1,3,2]dioxaphosphepin] 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.
