Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Ethyl (2S)-2-hydroxy-3-methylbutanoate (CAS 63674-18-0), a certified reference material (molecular formula C7H14O3, MW 146.18 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Ethyl (2S)-2-hydroxy-3-methylbutanoate is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 146.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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.
