Chemical Structure
Description
CATO supplies (3-([1,1'-Biphenyl]-4-yl)-2-(m-tolyl)isoxazolidin-5-yl)methanol (CAS 629643-15-8), a certified reference material (molecular formula C23H23NO2, MW 345.43 g/mol) for analytical method development and quality control.
The molecular framework of (3-([1,1'-Biphenyl]-4-yl)-2-(m-tolyl)isoxazolidin-5-yl)methanol (C23H23NO2) 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. 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.
As a certified reference material (CRM), (3-([1,1'-Biphenyl]-4-yl)-2-(m-tolyl)isoxazolidin-5-yl)methanol 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.
