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.
3-((4-Chloro-2-methylphenoxy)methyl)benzoic acid (CAS 832740-30-4), molecular formula C15H13ClO3 and molecular weight 276.71 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-((4-Chloro-2-methylphenoxy)methyl)benzoic acid (C15H13ClO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. 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), 3-((4-Chloro-2-methylphenoxy)methyl)benzoic acid 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.
