Chemical Structure
Description
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.
CATO supplies 3-(Trifluoromethyl)phenylacetic acid (alpha,alpha,alpha-trifluoro-m-tolyl)acetic acid 3-trifluoromethylphenylacetic acid m-trifluoromethylphenyl acetic acid 2-(3-(trifluoromethyl)phenyl)acetic acid 2-[3-(trifluoromethyl)phenyl]acetic acid (a,a,a-trifluoro-m-tolyl)acetic acid m-(trifluoromethyl)phenylacetic acid 351-35-9 (CAS 351-35-9), a certified reference material (molecular formula C9H13F3O2, MW 210.19 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, 3-(Trifluoromethyl)phenylacetic acid (alpha,alpha,alpha-trifluoro-m-tolyl)acetic acid 3-trifluoromethylphenylacetic acid m-trifluoromethylphenyl acetic acid 2-(3-(trifluoromethyl)phenyl)acetic acid 2-[3-(trifluoromethyl)phenyl]acetic acid (a,a,a-trifluoro-m-tolyl)acetic acid m-(trifluoromethyl)phenylacetic acid 351-35-9 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 210.19 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.
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.
