Chemical Structure
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-1,2,3,9-tetrahydropyrrolo[2,1-b]quinazoline.
CATO supplies 7-Bromo-1,2,3,9-tetrahydropyrrolo[2,1-b]quinazoline (CAS 61938-84-9), a certified reference material (molecular formula C11H11BrN2, MW 251.12 g/mol) for analytical method development and quality control.
Based on its molecular formula C11H11BrN2, 7-Bromo-1,2,3,9-tetrahydropyrrolo[2,1-b]quinazoline contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 251.12 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.
