2,4-Dihydroxybenzaldehyde (CAS 95-01-2)

2,4-Dihydroxybenzaldehyde is an aromatic aldehyde featuring two hydroxyl groups positioned at the 2nd and 4th places on a benzene ring, adjacent to an aldehyde group. This structural arrangement contributes to its chemical reactivity and ability to participate in various organic synthesis reactions. The presence of hydroxyl groups enhances its solubility in polar solvents and contributes to its antioxidant properties, due to their capability to donate hydrogen atoms and stabilize free radicals. In research contexts, 2,4-Dihydroxybenzaldehyde has been extensively used as a building block in synthetic chemistry for the production of more complex organic compounds. Its aldehyde group allows it to undergo condensation reactions with compounds containing amine groups, leading to the synthesis of Schiff bases, which are useful in a range of applications including the development of new materials, catalysts, and ligands in coordination chemistry. Additionally, this compound has been utilized in studies focusing on natural phenolic compounds derived from plants, where it serves as a model compound to understand the behavior of naturally occurring substances with similar structures. Researchers also investigate its potential role in polymer chemistry for creating polymers with specific properties such as UV-resistance and enhanced durability, leveraging its ability to form stable aromatic rings within polymer chains.
