Chemical Structure

1108233-34-6 3,4-Dihydroxy-N'-(2-hydroxybenzylidene)benzohydrazide Hemimethanolate Sesquihydrate 3,4-Dihydroxybenzoic Acid (2E)-2-[(2-Hydroxyphenyl)methylene]hydrazide Methanol Hydrate CAS 1108233-34-6 chemical structure

Description

The molecular framework of 1108233-34-6 3,4-Dihydroxy-N'-(2-hydroxybenzylidene)benzohydrazide Hemimethanolate Sesquihydrate 3,4-Dihydroxybenzoic Acid (2E)-2-[(2-Hydroxyphenyl)methylene]hydrazide Methanol Hydrate (C14H12N2O4CH4OH2O) is characterized by a flavonoid core, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
