Chemical Structure
Description
The occurrence of N-(3,5-Difluorobenzyl)-1-(2-fluoroethyl)-4-methyl-1H-pyrazol-3-amine hydrochloride is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N-(3,5-Difluorobenzyl)-1-(2-fluoroethyl)-4-methyl-1H-pyrazol-3-amine hydrochloride (CAS 1856034-12-2) is a high-purity analytical reference standard with the molecular formula C13H14F3N3HCl and a molecular weight of 305.73 g/mol.
Structurally, N-(3,5-Difluorobenzyl)-1-(2-fluoroethyl)-4-methyl-1H-pyrazol-3-amine hydrochloride (C13H14F3N3HCl) 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 305.73 g/mol, it falls into the moderately-high-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).
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.
