Chemical Structure

potassium;(2S)-3-hydroxy-2-methylpropanoate CAS 1402163-95-4 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 potassium;(2S)-3-hydroxy-2-methylpropanoate.

potassium;(2S)-3-hydroxy-2-methylpropanoate (CAS 1402163-95-4), molecular formula C4H7O3K and molecular weight 142.19 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, potassium;(2S)-3-hydroxy-2-methylpropanoate is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 142.19 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.
