Ortho-vanillin is a member of the class of benzaldehydes that is salicylaldehyde substituted by a methoxy group at position 3. It has a role as an antimutagen and a plant metabolite. It is a member of benzaldehydes and a member of guaiacols. It derives from a salicylaldehyde. In chemistry, 1,4-benzoquinonetetracarboxylic acid is an organic compound with formula, or (C6O2)(-(CO)OH)4, which can be viewed as deriving from ''para''-benzoquinone through replacement of the four hydrogen atoms by carboxyl functional groups -(CO)OH. In the presence of heat and acetic acid, ortho-toluidine (also called o-toluidine) reacts rapidly with aldohexoses (mostly glucose) to form a green-colored complex that can be measured at 630 nm.
