Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 269.51 g/mol gives 3-(2,4,5-Trichlorophenoxy)propanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-(2,4,5-Trichlorophenoxy)propanoic acid (CAS 582-53-6), a certified reference material (molecular formula C9H7Cl3O3, MW 269.51 g/mol) for analytical method development and quality control.
The molecular framework of 3-(2,4,5-Trichlorophenoxy)propanoic acid (C9H7Cl3O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
