1-(1-(2,2-Difluoroethyl)-5-methyl-1H-pyrazol-4-yl)-N-((5-fluorothiophen-2-yl)methyl)methanamine hydrochloride (CAS 1855938-07-6) is a high-purity analytical reference standard with the molecular formula C12H14F3N3SHCl and a molecular weight of 325.78 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution, 1-(1-(2,2-Difluoroethyl)-5-methyl-1H-pyrazol-4-yl)-N-((5-fluorothiophen-2-yl)methyl)methanamine hydrochloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 325.78 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
