Chemical Structure

1-(difluoromethyl)-1H-pyrazol-3-amine CAS 865663-99-6 chemical structure

Description

1-(difluoromethyl)-1H-pyrazol-3-amine (C4H5F2N3) contains a nitrile group, fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

1-(difluoromethyl)-1H-pyrazol-3-amine (CAS 865663-99-6) is a high-purity analytical reference standard with the molecular formula C4H5F2N3 and a molecular weight of 133.10 g/mol.

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.
