Chemical Structure

Ethyl 5-(difluoromethyl)-1,4,5,6-tetrahydrocyclopenta[c]pyrazole-3-carboxylate CAS 2433888-91-4 chemical structure

Description

As a certified reference material (CRM), Ethyl 5-(difluoromethyl)-1,4,5,6-tetrahydrocyclopenta[c]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 5-(difluoromethyl)-1,4,5,6-tetrahydrocyclopenta[c]pyrazole-3-carboxylate (CAS 2433888-91-4), molecular formula C10H12F2N2O2 and molecular weight 230.21 g/mol, is a CATO reference standard with documented purity and traceability.

Ethyl 5-(difluoromethyl)-1,4,5,6-tetrahydrocyclopenta[c]pyrazole-3-carboxylate (C10H12F2N2O2) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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