N-[(E)-(3-Phenyl-1H-pyrazol-4-yl)methylidene]-4-(trifluoromethyl)benzenecarbohydrazide CAS 477710-90-0

Description

Compared with other compounds in its class, the molecular weight of 358.32 g/mol gives N-[(E)-(3-Phenyl-1H-pyrazol-4-yl)methylidene]-4-(trifluoromethyl)benzenecarbohydrazide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

N-[(E)-(3-Phenyl-1H-pyrazol-4-yl)methylidene]-4-(trifluoromethyl)benzenecarbohydrazide (CAS 477710-90-0) is a high-purity analytical reference standard with the molecular formula C18H13F3N4O and a molecular weight of 358.32 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, N-[(E)-(3-Phenyl-1H-pyrazol-4-yl)methylidene]-4-(trifluoromethyl)benzenecarbohydrazide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 358.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
