Chemical Structure
Description
The molecular framework of 5-(4-Methoxyphenyl)imidazo[1,5-a]pyrazine-3-carboxylic acid (C14H11N3O3) 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).
5-(4-Methoxyphenyl)imidazo[1,5-a]pyrazine-3-carboxylic acid (CAS 1206969-05-2), molecular formula C14H11N3O3 and molecular weight 269.26 g/mol, is a CATO reference standard with documented purity and traceability.
