Chemical Structure

Ethyl 3-(methoxymethyl)-1-(trifluoromethyl)-1H-pyrazole-5-carboxylate CAS 2821786-30-3 chemical structure

Description

Ethyl 3-(methoxymethyl)-1-(trifluoromethyl)-1H-pyrazole-5-carboxylate (C9H11F3N2O3) 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, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

Ethyl 3-(methoxymethyl)-1-(trifluoromethyl)-1H-pyrazole-5-carboxylate (CAS 2821786-30-3) is a high-purity analytical reference standard with the molecular formula C9H11F3N2O3 and a molecular weight of 252.19 g/mol.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
