Chemical Structure
Description
CATO supplies Sodium (S)-2-hydroxy-3-methylbutanoate (CAS 54641-19-9), a certified reference material (molecular formula C5H9O3Na, MW 140.11 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Sodium (S)-2-hydroxy-3-methylbutanoate is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 140.11 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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.
