Chemical Structure

3-(1,1-Dioxido-2-isothiazolidinyl)benzoic Acid CAS 138099-41-9 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 3-(1,1-Dioxido-2-isothiazolidinyl)benzoic Acid.

CATO supplies 3-(1,1-Dioxido-2-isothiazolidinyl)benzoic Acid (CAS 138099-41-9), a certified reference material (molecular formula C10H11NO4S, MW 241.26 g/mol) for analytical method development and quality control.

3-(1,1-Dioxido-2-isothiazolidinyl)benzoic Acid (C10H11NO4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. 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.
