Chemical Structure

5-Bromo-N-cyclopropylthiophene-2-sulfonamide CAS 81597-70-8 chemical structure

Description

The occurrence of 5-Bromo-N-cyclopropylthiophene-2-sulfonamide is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 5-Bromo-N-cyclopropylthiophene-2-sulfonamide (CAS 81597-70-8), a certified reference material (molecular formula C7H8BrNO2S2, MW 282.18 g/mol) for analytical method development and quality control.

5-Bromo-N-cyclopropylthiophene-2-sulfonamide (C7H8BrNO2S2) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
