Chemical Structure
Description
CATO supplies 4-((4-Nitrobenzyl)oxy)-1,5-diphenyl-3-(trifluoromethyl)-1H-pyrazole (CAS 400086-85-3), a certified reference material (molecular formula C23H16F3N3O3, MW 439.39 g/mol) for analytical method development and quality control.
4-((4-Nitrobenzyl)oxy)-1,5-diphenyl-3-(trifluoromethyl)-1H-pyrazole (C23H16F3N3O3) contains a steroid core, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 4-((4-Nitrobenzyl)oxy)-1,5-diphenyl-3-(trifluoromethyl)-1H-pyrazole 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.
