4-[(2,3-Dimethylphenoxy)methyl]benzoic acid CAS 149288-32-4

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 4-[(2,3-Dimethylphenoxy)methyl]benzoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 256.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

4-[(2,3-Dimethylphenoxy)methyl]benzoic acid (CAS 149288-32-4) is a high-purity analytical reference standard with the molecular formula C16H16O3 and a molecular weight of 256.30 g/mol.

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), 4-[(2,3-Dimethylphenoxy)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.
