ortho- acetovanillon ( 2-hydroxy-3-methoxyacetophenone ) is an organic chemical compound with the empirical formula C ₉ H ₁₀ O ₃ , which is structurally derived from both acetophenone and guaiacol ( o-methoxyphenol ). It is a derivative of acetophenone with an additional hydroxyl and methoxy group . It differs from acetovanillon in the position of the hydroxyl group. The prefix ortho indicates the position of the hydroxyl group in relation to the acetyl group ; in acetovanillon these two groups are in the para position. The structural analogy corresponds to that between vanillin and ortho- vanillin .

ortho- acetovanillon	Acetovanillon

ortho- acetovanillon is obtained u. a. by isolation from reaction residues in the preparation of acetovanillon, as well as by ether cleavage of 2,3-dimethoxyacetophenone with aluminum chloride. The product forms long, pale yellow needles that melt at 53–54 ° C.
