Chemical Structure
Description
CATO supplies 4-bromoisoquinoline (CAS 1532-97-4), a certified reference material (molecular formula C9H16BrN, MW 218.13 g/mol) for analytical method development and quality control.
Based on its molecular formula C9H16BrN, 4-bromoisoquinoline contains a nitrile group, bromine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 218.13 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
