Questions And Answer | Back Directory | [Description]
2'-Hydroxyacetophenone is a flavouring ingredient. It is a typical flavour additive for cherry kernel, cinnamon, rum, tobacco, coumarin, and tropical fruit. Moreover, it can be used as the intermediate or raw material in organic synthesis. Specifically, this chemical may act as the raw material to prepare a Schiff's base al-alkoxide initiator that facilitates the controlled polymerization of DL-lactide.1 This substance can also function as the effective component in balsamic compounds for fabricating taste modifying compositions.2 Additionally, this chemical has been employed to react with benzoyl chloride for generating 2-(2-Amino-3-methoxyphenyl)-4-oxo-4H-[1]benzopyran, which exhibits good performance for treating cancer and other proliferative diseases such as psoriasis and restenosis.3 | [Reference]

2’Hydroxyacetophenone is a phenolic compound used in the synthesis of potential anti-myobacterial and anticancer agents. | [Definition]
ChEBI: 2'-Hydroxyacetophenone is a monohydroxyacetophenone that is acetophenone in which one of the hydrogens ortho to the acetyl group has been replaced by a hydroxy group. It has a role as a flavouring agent. It is a monohydroxyacetophenone and a member of phenols. | [Preparation]
Preparation by Fries rearrangement of phenyl acetate, with Lewis acids aluminium chloride. | [Aroma threshold values]
Detection: 5.5 ppm; aroma characteristics at 2.0%: phenolic, sharp, benzaldehyde, cherry pit, tropical,
melon with a tobacco afternote | [Taste threshold values]
Taste characteristics at 5.0 ppm: naphthyl, cinnamon, cherry pit, coumarin, phenolic, tobacco and honey. | [Synthesis Reference(s)]
