Chemical Structure

3-Bromopyridine-4-sulfonamide CAS 2095853-75-9 chemical structure

Description

The occurrence of 3-Bromopyridine-4-sulfonamide is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-Bromopyridine-4-sulfonamide (CAS 2095853-75-9), molecular formula C5H5BrN2O2S and molecular weight 237.07 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C5H5BrN2O2S, 3-Bromopyridine-4-sulfonamide contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 237.07 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), 3-Bromopyridine-4-sulfonamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
