Description
3’-Hydroxyacetophenone is a chemical compound and it is a component of castoreum, the exudate from the castor sacs of the mature beaver. It is used in the synthesis and preparation of chalcones and flavonoids as anti-tuberculosis agents, as well as antileishmanial chaocones.
Chemical Properties
beige-brown crystalline powder
Uses
Useful in the preparation of chalcones, flavonoids, and phenylephrine. It is an active component of castoreum, which is used as a tincture in some perfumes and as a food additive.

Flammability and Explosibility
Non flammable
Synthesis
General procedure for the synthesis of 3-hydroxyacetophenone from 3-iodoacetophenone: 3-iodoacetophenone (1.0 mmol), CuCl (13.4 mg, 0.1 mmol), KOH (336 mg, 6.0 mmol), ethylene glycol (12 μL, 0.2 mmol), and a solvent mixture of DMSO/HO were sequentially added to the test tube fitted with a magnetic stirrer ( 1.0 mL/0.5 mL). The reaction mixture was placed in a preheated 120 °C oil bath under argon protection and stirred for 24 hours. After completion of the reaction, it was cooled to room temperature and the reaction mixture was extracted by partitioning with 5% HCl aqueous solution and ethyl acetate. The organic phase was washed sequentially with water and saturated saline, dried over anhydrous MgSO and concentrated under reduced pressure to remove the solvent. The crude product was further purified by column chromatography (eluent: EtOAc/hexane) to afford the target product 3-hydroxyacetophenone.
