2-Methyl-3-(2,2,2-trifluoroacetamido)propanoic acid CAS 101642-73-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Methyl-3-(2,2,2-trifluoroacetamido)propanoic acid.

2-Methyl-3-(2,2,2-trifluoroacetamido)propanoic acid (CAS 101642-73-3) is a high-purity analytical reference standard with the molecular formula C6H8F3NO3 and a molecular weight of 199.13 g/mol.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, 2-Methyl-3-(2,2,2-trifluoroacetamido)propanoic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 199.13 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.

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.
