Chemical Structure
Description
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 supplies Methyl 3-(2-(benzyloxy)-5-bromophenyl)-3-phenylpropanoate (CAS 156755-24-7), a certified reference material (molecular formula C23H21BrO3, MW 425.32 g/mol) for analytical method development and quality control.
The molecular framework of Methyl 3-(2-(benzyloxy)-5-bromophenyl)-3-phenylpropanoate (C23H21BrO3) is characterized by a steroid core, a hydroxyl group, an ether linkage, bromine substitution. 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).
As a certified reference material (CRM), Methyl 3-(2-(benzyloxy)-5-bromophenyl)-3-phenylpropanoate 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.
