Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2S,2'S,3S,3'S)-3,3'-di-tertbutyl-4,4'-bis((S)-2-methyl1-phenylpropoxy)-2,2',3,3'tetrahydro-2,2'-bibenzo[d][1,3]oxaphosphole.

CATO supplies (2S,2'S,3S,3'S)-3,3'-di-tertbutyl-4,4'-bis((S)-2-methyl1-phenylpropoxy)-2,2',3,3'tetrahydro-2,2'-bibenzo[d][1,3]oxaphosphole (CAS 2169292-11-7), a certified reference material (molecular formula C42H52O4P2, MW 682.81 g/mol) for analytical method development and quality control.

Structurally, (2S,2'S,3S,3'S)-3,3'-di-tertbutyl-4,4'-bis((S)-2-methyl1-phenylpropoxy)-2,2',3,3'tetrahydro-2,2'-bibenzo[d][1,3]oxaphosphole (C42H52O4P2) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 17.0, corresponding to approximately 17 ring(s) or double-bond equivalent(s). With a molecular weight of 682.81 g/mol, it falls into the high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 (2S,2'S,3S,3'S)-3,3'-di-tertbutyl-4,4'-bis((S)-2-methyl1-phenylpropoxy)-2,2',3,3'tetrahydro-2,2'-bibenzo[d][1,3]oxaphosphole 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.
