Chemical Structure
Description
Ethyl 1-phenyl-5-(1H-pyrrol-1-yl)-1H-pyrazole-4-carboxylate (CAS 94692-05-4) is a high-purity analytical reference standard with the molecular formula C16H15N3O2 and a molecular weight of 281.31 g/mol.
The molecular framework of Ethyl 1-phenyl-5-(1H-pyrrol-1-yl)-1H-pyrazole-4-carboxylate (C16H15N3O2) is characterized by a nitrogen-containing heterocyclic scaffold, 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.
