Chemical Structure

(S)-2-Hydroxybutanoic acid CAS 3347-90-8 chemical structure

Description

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

(S)-2-Hydroxybutanoic acid (CAS 3347-90-8) is a high-purity analytical reference standard with the molecular formula C4H8O3 and a molecular weight of 104.10 g/mol.

(S)-2-Hydroxybutanoic acid (C4H8O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.
