Chemical Structure

2,4-Thiazolidinedione, potassium salt (1:1) CAS 39131-10-7 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

2,4-Thiazolidinedione, potassium salt (1:1) (CAS 39131-10-7) is a high-purity analytical reference standard with the molecular formula C3H2NO2SK and a molecular weight of 155.21 g/mol.

Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 2,4-Thiazolidinedione, potassium salt (1:1) is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 155.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.
