Chemical Structure
Description
(5-Bromothiophen-2-yl)methanamine hydrobromide (CAS 1289191-38-3), molecular formula C5H6BrNSHBr and molecular weight 272.99 g/mol, is a CATO reference standard with documented purity and traceability.
(5-Bromothiophen-2-yl)methanamine hydrobromide (C5H6BrNSHBr) contains a nitrile group, sulfur-containing functionality, bromine substitution. Halogen substitution raises its density and boiling point; 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.
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.
