2,4-Dimethoxybenzaldehyde (DMBA) is a reagent used to specifically quantify phlorotannins. This product reacts specifically with 1,3-and 1,3,5-substituted phenols (e.g., phlorotannins) to form a colored product.
2,4-Dihydroxybenzaldehyde or β-resorcylaldehyde is a phenolic aldehyde, a chemical compound with the formula C 7 H 6 O 3. It is an isomer of protocatechuic aldehyde (3,4-dihydroxybenzaldehyde). References
The systematic name of this enzyme class is 1,2-bis(3,4-dimethoxyphenyl)propane-1,3-diol:hydrogen-peroxide oxidoreductase.

The aza-Henry reaction is also used to produce nitroamines and can be a reliable synthetic route for the synthesis of vicinal diamines. [13] Perhaps one of the most synthetically useful modifications to the Henry reaction is the use of an organocatalyst. [2] [12] [14] The catalytic cycle is shown below. Henry reaction synthetic scheme
The term aldol condensation is also commonly used, especially in biochemistry, to refer to just the first (addition) stage of the process—the aldol reaction itself—as catalyzed by aldolases. However, the first step is formally an addition reaction rather than a condensation reaction because it does not involve the loss of a small molecule.

2,4-Dihydroxybenzoic acid (β-resorcylic acid) is a dihydroxybenzoic acid. As a resorcylic acid, it is one of the three isomeric crystalline acids that are both carboxyl derivatives of resorcinol and dihydroxy derivatives of benzoic acid. [4] Synthesis from resorcinol is via the Kolbe-Schmitt reaction. [5]
