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 6-Bromo-2,3,4,5-tetrahydro-1H-benzo[c]azepine.
6-Bromo-2,3,4,5-tetrahydro-1H-benzo[c]azepine (CAS 1781614-18-3), molecular formula C10H12BrN and molecular weight 226.11 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C10H12BrN, 6-Bromo-2,3,4,5-tetrahydro-1H-benzo[c]azepine 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 226.11 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
