Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Isobutyl-3-(trifluoromethyl)-1H-pyrazole.
1-Isobutyl-3-(trifluoromethyl)-1H-pyrazole (CAS 1437795-15-7) is a high-purity analytical reference standard with the molecular formula C8H11F3N2 and a molecular weight of 192.18 g/mol.
Based on its molecular formula C8H11F3N2, 1-Isobutyl-3-(trifluoromethyl)-1H-pyrazole contains a nitrile group, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 192.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
