Chemical Structure

2,2,3-Trichloropropanoic acid CAS 3278-46-4 chemical structure

Description

CATO supplies 2,2,3-Trichloropropanoic acid (CAS 3278-46-4), a certified reference material (molecular formula C3H3Cl3O2, MW 177.41 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 2,2,3-Trichloropropanoic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 177.41 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), 2,2,3-Trichloropropanoic 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.
