Chemical Structure

1-(Difluoromethyl)-N-(3-fluorobenzyl)-3-methyl-1H-pyrazol-4-amine hydrochloride CAS 1855950-76-3 chemical structure

Description

The occurrence of 1-(Difluoromethyl)-N-(3-fluorobenzyl)-3-methyl-1H-pyrazol-4-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.

1-(Difluoromethyl)-N-(3-fluorobenzyl)-3-methyl-1H-pyrazol-4-amine hydrochloride (CAS 1855950-76-3), molecular formula C12H12F3N3HCl and molecular weight 291.70 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution, 1-(Difluoromethyl)-N-(3-fluorobenzyl)-3-methyl-1H-pyrazol-4-amine hydrochloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 291.70 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
