methyl ester; (2S)-3,3,3-trifluoro-2-hydroxy-2-methylpropanoic acid (CAS 24435-45-8), molecular formula C4H5F3O3 and molecular weight 158.08 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, methyl ester; (2S)-3,3,3-trifluoro-2-hydroxy-2-methylpropanoic acid (C4H5F3O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 158.08 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
