Chemical Structure
Description
The molecular framework of 9-(2-Bromo-5-chlorophenyl)-9H-carbazole (C18H11BrClN) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
9-(2-Bromo-5-chlorophenyl)-9H-carbazole (CAS 1361956-35-5), molecular formula C18H11BrClN and molecular weight 356.64 g/mol, is a CATO reference standard with documented purity and traceability.
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.
