CATO supplies Methyl (3E)-2-{1-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-1H-indol-3-yl}-3-{[(4-nitrophenyl)methoxy]imino}propanoate (CAS 303152-89-8), a certified reference material (molecular formula C25H18ClF3N4O5, MW 546.88 g/mol) for analytical method development and quality control.
Methyl (3E)-2-{1-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-1H-indol-3-yl}-3-{[(4-nitrophenyl)methoxy]imino}propanoate (C25H18ClF3N4O5) contains a flavonoid 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, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
