Chemical Structure

1-(Difluoromethyl)-N-(4-methoxybenzyl)-3-methyl-1H-pyrazol-4-amine hydrochloride CAS 1856058-57-5 chemical structure

Description

The occurrence of 1-(Difluoromethyl)-N-(4-methoxybenzyl)-3-methyl-1H-pyrazol-4-amine hydrochloride is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(Difluoromethyl)-N-(4-methoxybenzyl)-3-methyl-1H-pyrazol-4-amine hydrochloride (CAS 1856058-57-5) is a high-purity analytical reference standard with the molecular formula C13H15F2N3OHCl and a molecular weight of 303.74 g/mol.

The molecular framework of 1-(Difluoromethyl)-N-(4-methoxybenzyl)-3-methyl-1H-pyrazol-4-amine hydrochloride (C13H15F2N3OHCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
