Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Ethyl 5-bromo-3-chloro-1H-indole-2-carboxylate (CAS 91062-61-2), a certified reference material (molecular formula C11H9BrClNO2, MW 302.55 g/mol) for analytical method development and quality control.
Based on its molecular formula C11H9BrClNO2, Ethyl 5-bromo-3-chloro-1H-indole-2-carboxylate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 302.55 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
