Description
CATO supplies 9-(2-Bromo-3-chlorophenyl)-9H-carbazole (CAS 2126841-70-9), a certified reference material (molecular formula C18H11BrClN, MW 356.64 g/mol) for analytical method development and quality control.
Based on its molecular formula C18H11BrClN, 9-(2-Bromo-3-chlorophenyl)-9H-carbazole contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 356.64 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
