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 3-([1,1'-Biphenyl]-4-yl)-5-phenyl-2-(m-tolyl)isoxazolidine.
3-([1,1'-Biphenyl]-4-yl)-5-phenyl-2-(m-tolyl)isoxazolidine (CAS 629643-11-4) is a high-purity analytical reference standard with the molecular formula C28H25NO and a molecular weight of 391.50 g/mol.
The molecular framework of 3-([1,1'-Biphenyl]-4-yl)-5-phenyl-2-(m-tolyl)isoxazolidine (C28H25NO) is characterized by a steroid core, an amide 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), 3-([1,1'-Biphenyl]-4-yl)-5-phenyl-2-(m-tolyl)isoxazolidine 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.
