Chemical Structure

Ethyl 4-(3-(trifluoromethyl)-1h-pyrazol-1-yl)butanoate CAS 1174860-75-3 chemical structure

Description

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

Ethyl 4-(3-(trifluoromethyl)-1h-pyrazol-1-yl)butanoate (CAS 1174860-75-3) is a high-purity analytical reference standard with the molecular formula C10H13F3N2O2 and a molecular weight of 250.22 g/mol.

Ethyl 4-(3-(trifluoromethyl)-1h-pyrazol-1-yl)butanoate (C10H13F3N2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
