N-(3,5-Difluorobenzyl)-1-(2-fluoroethyl)-5-methyl-1H-pyrazol-4-amine hydrochloride CAS 1855938-75-8 chemical structure

Description

CATO manufactures N-(3,5-Difluorobenzyl)-1-(2-fluoroethyl)-5-methyl-1H-pyrazol-4-amine hydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

N-(3,5-Difluorobenzyl)-1-(2-fluoroethyl)-5-methyl-1H-pyrazol-4-amine hydrochloride (CAS 1855938-75-8), molecular formula C13H14F3N3HCl and molecular weight 305.73 g/mol, is a CATO reference standard with documented purity and traceability.

N-(3,5-Difluorobenzyl)-1-(2-fluoroethyl)-5-methyl-1H-pyrazol-4-amine hydrochloride (C13H14F3N3HCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
