Chemical Structure

Ethyl 2-{3,5-dimethyl-1-[3-(trifluoromethyl)phenyl]-1h-pyrazol-4-yl}-2-oxoacetate CAS 956438-46-3 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 2-{3,5-dimethyl-1-[3-(trifluoromethyl)phenyl]-1h-pyrazol-4-yl}-2-oxoacetate (CAS 956438-46-3) is a high-purity analytical reference standard with the molecular formula C16H15F3N2O3 and a molecular weight of 340.30 g/mol.

The molecular framework of Ethyl 2-{3,5-dimethyl-1-[3-(trifluoromethyl)phenyl]-1h-pyrazol-4-yl}-2-oxoacetate (C16H15F3N2O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO manufactures Ethyl 2-{3,5-dimethyl-1-[3-(trifluoromethyl)phenyl]-1h-pyrazol-4-yl}-2-oxoacetate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
