Chemical Structure

di-tert-butyl((2S,3S)-3-(tert-butyl)-4-phenoxy-2,3-dihydrobenzo[d][1,3]oxaphosphol-2-yl)phosphine oxide CAS 2374143-31-2 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 di-tert-butyl((2S,3S)-3-(tert-butyl)-4-phenoxy-2,3-dihydrobenzo[d][1,3]oxaphosphol-2-yl)phosphine oxide.

CATO supplies di-tert-butyl((2S,3S)-3-(tert-butyl)-4-phenoxy-2,3-dihydrobenzo[d][1,3]oxaphosphol-2-yl)phosphine oxide (CAS 2374143-31-2), a certified reference material (molecular formula C25H36O3P2, MW 446.50 g/mol) for analytical method development and quality control.

The molecular framework of di-tert-butyl((2S,3S)-3-(tert-butyl)-4-phenoxy-2,3-dihydrobenzo[d][1,3]oxaphosphol-2-yl)phosphine oxide (C25H36O3P2) is characterized by a steroid core, a phosphonate group, a hydroxyl group, an ether linkage. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), di-tert-butyl((2S,3S)-3-(tert-butyl)-4-phenoxy-2,3-dihydrobenzo[d][1,3]oxaphosphol-2-yl)phosphine oxide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
