Chemical Structure

Ethyl 4-iodo-5-(trifluoromethyl)-1H-pyrazole-3-carboxylate CAS 2137471-63-5 chemical structure

Description

As a certified reference material (CRM), Ethyl 4-iodo-5-(trifluoromethyl)-1H-pyrazole-3-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

Ethyl 4-iodo-5-(trifluoromethyl)-1H-pyrazole-3-carboxylate (CAS 2137471-63-5), molecular formula C7H6F3IN2O2 and molecular weight 334.03 g/mol, is a CATO reference standard with documented purity and traceability.

Ethyl 4-iodo-5-(trifluoromethyl)-1H-pyrazole-3-carboxylate (C7H6F3IN2O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/iodine substitution, an aromatic ring system. 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).

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.
