Chemical Structure
Description
7-Bromo-2,3,4,4a,9,9a-hexahydro-1H-pyrido[3,4-b]indol-1-one (CAS 1189545-87-6), molecular formula C11H9BrN2O and molecular weight 265.11 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H9BrN2O, 7-Bromo-2,3,4,4a,9,9a-hexahydro-1H-pyrido[3,4-b]indol-1-one contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 265.11 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.
