Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
ethyl 6-bromopyrrolo[2,1-b]thiazole-7-carboxylate (CAS 1108172-91-3), molecular formula C9H14BrNO2S and molecular weight 280.18 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, ethyl 6-bromopyrrolo[2,1-b]thiazole-7-carboxylate is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 280.18 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.
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.
