Chemical Structure

74519-39-4 A838157 N-(4-methylphenyl)-2-oxidanylidene-propanehydrazonoyl bromide N-(4-methylphenyl)-2-oxopropanehydrazonoyl bromide CAS 74519-39-4 chemical structure

Description

The molecular framework of 74519-39-4 A838157 N-(4-methylphenyl)-2-oxidanylidene-propanehydrazonoyl bromide N-(4-methylphenyl)-2-oxopropanehydrazonoyl bromide (C10H11BrN2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).
