Chemical Structure
Description
The occurrence of 3-Bromo-6-chloro-2-methyl-1H-pyrrolo[2,3-b]pyridine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Bromo-6-chloro-2-methyl-1H-pyrrolo[2,3-b]pyridine (CAS 1936487-25-0), molecular formula C8H6BrClN2 and molecular weight 245.50 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C8H6BrClN2, 3-Bromo-6-chloro-2-methyl-1H-pyrrolo[2,3-b]pyridine 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 245.50 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
