Chemical Structure

1-(difluoromethyl)-1H-pyrazol-5-amine CAS 1952307-22-0 chemical structure

Description

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.

1-(difluoromethyl)-1H-pyrazol-5-amine (CAS 1952307-22-0) is a high-purity analytical reference standard with the molecular formula C4H9F2N3 and a molecular weight of 137.13 g/mol.

The molecular framework of 1-(difluoromethyl)-1H-pyrazol-5-amine (C4H9F2N3) is characterized by fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
