Chemical Structure
Description
Ethyl 1-phenyl-5-(phenylamino)-1H-imidazole-4-carboxylate (CAS 68695-58-9) is a high-purity analytical reference standard with the molecular formula C18H16N3O2 and a molecular weight of 306.34 g/mol.
The molecular framework of Ethyl 1-phenyl-5-(phenylamino)-1H-imidazole-4-carboxylate (C18H16N3O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
