2-Hydroxy-2-(2,4,5-trichlorophenyl)acetic acid CAS 14299-51-5

Description

CATO supplies 2-Hydroxy-2-(2,4,5-trichlorophenyl)acetic acid (CAS 14299-51-5), a certified reference material (molecular formula C8H5Cl3O3, MW 255.48 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 2-Hydroxy-2-(2,4,5-trichlorophenyl)acetic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 255.48 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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-Hydroxy-2-(2,4,5-trichlorophenyl)acetic 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.
