Description
CATO supplies 1-(Difluoromethyl)-N-((3-methyl-1-propyl-1H-pyrazol-5-yl)methyl)-1H-pyrazol-3-amine hydrochloride (CAS 1856033-70-9), a certified reference material (molecular formula C12H17F2N5HCl, MW 305.76 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution, 1-(Difluoromethyl)-N-((3-methyl-1-propyl-1H-pyrazol-5-yl)methyl)-1H-pyrazol-3-amine hydrochloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 305.76 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
