Chemical Structure
Description
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.
CATO supplies (4-methylphenoxy)acetic acid 940-64-7 InChI=1/C9H10O3/c1-7-2-4-8(5-3-7)12-6-9(10)11/h2-5H,6H2,1H3,(H,10,11 acetic acid, (4-methylphenoxy)- (CAS 940-64-7), a certified reference material (molecular formula C9H10O3, MW 166.17 g/mol) for analytical method development and quality control.
The molecular framework of (4-methylphenoxy)acetic acid 940-64-7 InChI=1/C9H10O3/c1-7-2-4-8(5-3-7)12-6-9(10)11/h2-5H,6H2,1H3,(H,10,11 acetic acid, (4-methylphenoxy)- (C9H10O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, 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.
