8-Bromo-5-methyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole (CAS 1243389-52-7) is a high-purity analytical reference standard with the molecular formula C12H13BrN2 and a molecular weight of 265.15 g/mol.
Structurally, 8-Bromo-5-methyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole (C12H13BrN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 265.15 g/mol, it falls into the medium-molecular-weight range. 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.
