Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 9-(2'-Bromo-4-biphenylyl)carbazole.
9-(2'-Bromo-4-biphenylyl)carbazole (CAS 1215228-57-1) is a high-purity analytical reference standard with the molecular formula C24H16BrN and a molecular weight of 398.29 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution, 9-(2'-Bromo-4-biphenylyl)carbazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 398.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
