Chemical Structure
Description
The molecular framework of Methyl 2,6-Dihydroxy-4-Methoxybenzoate (C9H10O5) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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).
