Chemical Structure
Description
5-Bromo-2-phenyl-3-(pyridin-2-yl)-1H-indole (CAS 94107-54-7) is a high-purity analytical reference standard with the molecular formula C19H13BrN2 and a molecular weight of 349.22 g/mol.
5-Bromo-2-phenyl-3-(pyridin-2-yl)-1H-indole (C19H13BrN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
