Chemical Structure
Description
The molecular framework of 4-(2-methoxyphenyl)-6-methyl-isoxazolo[5,4-b]pyridin-3-amine (C14H13N3O2) 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).
4-(2-methoxyphenyl)-6-methyl-isoxazolo[5,4-b]pyridin-3-amine (CAS 1226227-45-7) is a high-purity analytical reference standard with the molecular formula C14H13N3O2 and a molecular weight of 255.27 g/mol.
