1. Used in the manufacture of choleretic and other organic synthetic raw materials. Animal experiments show that this product can increase the secretion of bile in rats, and also increase the discharge of solids, bile acid and bilirubin in bile, and also have the same effect on liver damage caused by carbon tetrachloride. Commonly used as an adjunct to cholecystitis and the treatment of acute and chronic jaundice hepatitis, but the application must comply with the doctor’s advice. This product is clinically used for the treatment of hepatitis and has a certain effect on yellowing. Therefore, it is harmful to swallow this product, and the contact is irritating to the eyes, respiratory system and skin.

2. This product is an organic synthesis intermediate used in the production of spices. The main synthesis of a-bromo-p-hydroxyacetophenone is an important intermediate for the synthesis of a selective B l receptor blocker, atenolol.

3. 4′-Hydroxyacetophenone is mainly used as a preservative in cosmetics. Due to its weak molecular activity, high temperature resistance, melting point of 95-97 ° C, and boiling point of 296 ° C, it is widely used in various liquid pharmaceuticals, which can prolong the shelf life of other active ingredients under high temperature conditions. It is currently a high temperature auxiliary active stabilizer in the pharmaceutical industry.

4.4′-Hydroxyacetophenonehas the following characteristics in cosmetics:

1) has a certain anti-corrosion ability;

2) has a strong ability to kill Aspergillus niger;

3) has a certain inhibitory effect on Pseudomonas aeruginosa cells. In addition, it is reported in the literature that it is compounded with 1,2-hexanediol and traditional Chinese medicine composition; the compounded composition has good antiseptic effect, no harm to human skin, and overcomes the current preservative damage to human skin. defect
