Chemical Structure
Description
CATO supplies 6-bromo-5-methyl-1,3-dihydro-2H-imidazo[4,5-b]pyridine-2-thione (CAS 104685-80-5), a certified reference material (molecular formula C7H6BrN3S, MW 244.11 g/mol) for analytical method development and quality control.
Owing to a nitrile group, sulfur-containing functionality, bromine substitution, an aromatic ring system, 6-bromo-5-methyl-1,3-dihydro-2H-imidazo[4,5-b]pyridine-2-thione is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 244.11 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 6-bromo-5-methyl-1,3-dihydro-2H-imidazo[4,5-b]pyridine-2-thione 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.
