Chemical Structure
Description
3,3,3-Trifluoro-<SC>DL</SC>-alanine (CAS 17463-43-3) is a high-purity analytical reference standard with the molecular formula C3H4F3NO2 and a molecular weight of 143.06 g/mol.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, 3,3,3-Trifluoro-<SC>DL</SC>-alanine is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 143.06 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
