Chemical Structure
Description
The occurrence of 3-Bromo-1H-pyrazol-4-amine hydrobromide is closely related to a nitrile group, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Bromo-1H-pyrazol-4-amine hydrobromide (CAS 1374320-70-3) is a high-purity analytical reference standard with the molecular formula C3H4BrN3HBr and a molecular weight of 242.90 g/mol.
3-Bromo-1H-pyrazol-4-amine hydrobromide (C3H4BrN3HBr) 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.
