Chemical Structure
Description
The molecular framework of 2-(4-((2-Ethyl-5,7-dimethyl-3H-imidazo[4,5-b]pyridin-3-yl)methyl)-2,6-dipropylphenoxy)-2-phenylacetic acid (C31H37N3O3) 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).
2-(4-((2-Ethyl-5,7-dimethyl-3H-imidazo[4,5-b]pyridin-3-yl)methyl)-2,6-dipropylphenoxy)-2-phenylacetic acid (CAS 153275-22-0), molecular formula C31H37N3O3 and molecular weight 499.64 g/mol, is a CATO reference standard with documented purity and traceability.
