Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 228.66 g/mol gives 1-(4-fluorophenyl)-5-methyl-1H-1,2,3-triazol-4-amine hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-(4-fluorophenyl)-5-methyl-1H-1,2,3-triazol-4-amine hydrochloride (CAS 1955499-10-1) is a high-purity analytical reference standard with the molecular formula C9H9FN4HCl and a molecular weight of 228.66 g/mol.
1-(4-fluorophenyl)-5-methyl-1H-1,2,3-triazol-4-amine hydrochloride (C9H9FN4HCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine 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.
