Chemical Structure
Description
Based on its molecular formula C9H7Br2N3HCl, 3-(2,5-Dibromophenyl)-1H-pyrazol-5-amine hydrochloride 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 353.44 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.
3-(2,5-Dibromophenyl)-1H-pyrazol-5-amine hydrochloride (CAS 1031793-70-0), molecular formula C9H7Br2N3HCl and molecular weight 353.44 g/mol, is a CATO reference standard with documented purity and traceability.
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.
