Chemical Structure

methyl (2S)-5-sulfanylidenepyrrolidine-2-carboxylate CAS 85178-37-6 chemical structure

Description

CATO supplies methyl (2S)-5-sulfanylidenepyrrolidine-2-carboxylate (CAS 85178-37-6), a certified reference material (molecular formula C6H9NO2S, MW 159.21 g/mol) for analytical method development and quality control.

methyl (2S)-5-sulfanylidenepyrrolidine-2-carboxylate (C6H9NO2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
