4'-Hydroxyacetophenone Chemical Properties,Uses,Production

Chemical Properties

almost white to beige crystalline powder

Chemical Properties

White to beige powder; sweet, hawthorn, balsam, mimosa aroma

Occurrence

Reported found in cloudberry, coffee, cranberry, mango, sherry, and wort.

Uses

4?-Hydroxyacetophenone has been used as ketone component in the preparation of 1-aryl-3-phenethylamino-1-propanone hydrochlorides, potential cytotoxic agents, via Mannich reactions.

Uses

4′-Hydroxyacetophenone has been used as ketone component in the preparation of 1-aryl-3-phenethylamino-1-propanone hydrochlorides, potential cytotoxic agents, via Mannich reactions.

Uses

p-Hydroxyacetophenone is widely used in medicine, cosmetics and industrial fields. It is a natural plant extract, which naturally exists in the stems and leaves of the Compositae plant, Artemisia annua, the roots of plants such as Artemisia annua, Rhododendron, and Panax ginseng. It has a good effect on yellow eyes caused by diseases such as hepatitis, and also has a good auxiliary effect on yellow eyes caused by various reasons. 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 and can prolong the shelf life of other active ingredients under high temperature conditions. It has no harm to human skin and is the safest high-temperature auxiliary active stabilizer in the pharmaceutical industry.
