Chemical Structure

Methyl (S)-3-chloro-2-methylpropanoate CAS 98190-86-4 chemical structure

Description

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.

CATO supplies Methyl (S)-3-chloro-2-methylpropanoate (CAS 98190-86-4), a certified reference material (molecular formula C5H9ClO2, MW 136.58 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, Methyl (S)-3-chloro-2-methylpropanoate is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 136.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
