Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-Bromo-5-methyl-4-oxo-4,5-dihydrothieno[3,2-c]pyridine-2-carbaldehyde, 97%.
CATO supplies 7-Bromo-5-methyl-4-oxo-4,5-dihydrothieno[3,2-c]pyridine-2-carbaldehyde, 97% (CAS 1610520-29-0), a certified reference material (molecular formula C9H6BrNO2S, MW 272.12 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution, 7-Bromo-5-methyl-4-oxo-4,5-dihydrothieno[3,2-c]pyridine-2-carbaldehyde, 97% is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 272.12 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.
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.
