Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-(p-Tolyl)-3-(trifluoromethyl)-1H-pyrazol-5-amine hydrochloride (CAS 1238864-82-8) is a high-purity analytical reference standard with the molecular formula C11H10F3N3HCl and a molecular weight of 277.67 g/mol.
Structurally, 4-(p-Tolyl)-3-(trifluoromethyl)-1H-pyrazol-5-amine hydrochloride (C11H10F3N3HCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 277.67 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
