Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(2,5-Difluorobenzyl)-3-methoxy-1-methyl-1H-pyrazol-4-amine hydrochloride.
CATO supplies N-(2,5-Difluorobenzyl)-3-methoxy-1-methyl-1H-pyrazol-4-amine hydrochloride (CAS 1856065-76-3), a certified reference material (molecular formula C12H13F2N3OHCl, MW 289.71 g/mol) for analytical method development and quality control.
The molecular framework of N-(2,5-Difluorobenzyl)-3-methoxy-1-methyl-1H-pyrazol-4-amine hydrochloride (C12H13F2N3OHCl) 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
