Chemical Structure
Description
CATO supplies 2-[4-(4-Chlorophenoxy)phenoxy]propanoicacid (CAS 26129-32-8), a certified reference material (molecular formula C15H13ClO4, MW 292.71 g/mol) for analytical method development and quality control.
The molecular framework of 2-[4-(4-Chlorophenoxy)phenoxy]propanoicacid (C15H13ClO4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, chlorine 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 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), 2-[4-(4-Chlorophenoxy)phenoxy]propanoicacid 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.
