Chemical Structure

3-bromothieno[3,2-b]pyridine-6-sulfonyl chloride CAS 1909318-96-2 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-bromothieno[3,2-b]pyridine-6-sulfonyl chloride.

CATO supplies 3-bromothieno[3,2-b]pyridine-6-sulfonyl chloride (CAS 1909318-96-2), a certified reference material (molecular formula C7H3BrClNO2S2, MW 312.59 g/mol) for analytical method development and quality control.

3-bromothieno[3,2-b]pyridine-6-sulfonyl chloride (C7H3BrClNO2S2) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/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. 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-bromothieno[3,2-b]pyridine-6-sulfonyl chloride 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.
