3-{1-[4-chloro-3-(trifluoromethyl)phenyl]-2,5-dimethyl-1h-pyrrol-3-yl}-2-cyanoprop-2-enoic acid CAS 743440-55-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 368.74 g/mol gives 3-{1-[4-chloro-3-(trifluoromethyl)phenyl]-2,5-dimethyl-1h-pyrrol-3-yl}-2-cyanoprop-2-enoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-{1-[4-chloro-3-(trifluoromethyl)phenyl]-2,5-dimethyl-1h-pyrrol-3-yl}-2-cyanoprop-2-enoic acid (CAS 743440-55-3) is a high-purity analytical reference standard with the molecular formula C17H12ClF3N2O2 and a molecular weight of 368.74 g/mol.

3-{1-[4-chloro-3-(trifluoromethyl)phenyl]-2,5-dimethyl-1h-pyrrol-3-yl}-2-cyanoprop-2-enoic acid (C17H12ClF3N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine 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.

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.

CATO manufactures 3-{1-[4-chloro-3-(trifluoromethyl)phenyl]-2,5-dimethyl-1h-pyrrol-3-yl}-2-cyanoprop-2-enoic acid 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.
