Description

Compared with other compounds in its class, the molecular weight of 222.17 g/mol gives 4-Amino-3-methyl-1-(2,2,2-trifluoroethyl)-1H-pyrazole-5-carboxamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Amino-3-methyl-1-(2,2,2-trifluoroethyl)-1H-pyrazole-5-carboxamide (CAS 89239-97-4) is a high-purity analytical reference standard with the molecular formula C7H9F3N4O and a molecular weight of 222.17 g/mol.

Owing to an amide group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 4-Amino-3-methyl-1-(2,2,2-trifluoroethyl)-1H-pyrazole-5-carboxamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 222.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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

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.
