Chemical Structure
Description
The occurrence of 5-bromo-2-methyl-2H-indazol-7-amine is closely related to a nitrile group, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-bromo-2-methyl-2H-indazol-7-amine (CAS 1896679-98-3), molecular formula C8H16BrN3 and molecular weight 234.14 g/mol, is a CATO reference standard with documented purity and traceability.
5-bromo-2-methyl-2H-indazol-7-amine (C8H16BrN3) contains a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
