Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 1,4-Dimethyl-3-phenyl-1H-pyrazol-5-amine hydrochloride is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 223.70 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.
1,4-Dimethyl-3-phenyl-1H-pyrazol-5-amine hydrochloride (CAS 138950-42-2), molecular formula C11H13N3HCl and molecular weight 223.70 g/mol, is a CATO reference standard with documented purity and traceability.
