Product Introduction:

P-Hydroxyacetophenone, also known as 4-Hydroxyacetophenone, 4-Acetylphenol, commonly known as acitrin.

It is white needle-like crystal at room temperature, flammable, easily soluble in hot water, methanol, ethanol, ether, acetone, benzene, and insoluble in petroleum ether.

It naturally exists in the stems and leaves of the Compositae plant, Artemisia annua L., and the roots of plants such as Artemisia annua L.

Animal experiments show that P-Hydroxyacetophenone can increase the secretion of bile in rats.

At the same time, it can also increase the excretion of solids, bile acid and bilirubin in bile, and has the same effect on liver damage caused by carbon tetrachloride.

P-Hydroxyacetophenone is used in the manufacture of choleretic drugs and other raw materials for organic synthesis.

Product Usage:

P-Hydroxyacetophenone is generally used to synthesize pharmaceutical intermediates (α-bromo-p-hydroxyacetophenone, choleretic drugs, antipyretic analgesics, etc.), others (spice, feed, etc.; pesticides, dyes, liquid crystal materials, etc.).

used as a preservative

p-Hydroxyacetophenone is the most safe high-temperature complementary energetic stabilizer in the pharmaceutical sector.

It is often used as a preservative in cosmetics and has no harm to the human body or the skin.

For most cosmetics, to ensure the hygiene and safety within the period of use, no preservatives can be added, but no antiseptic system is required, and the problem of bacteriostasis cannot be ignored.

P-Hydroxyacetophenone is mainly used as a preservative in cosmetics, and has anti-oxidation, sedative and soothing functions, and has synergistic effects when combined with other preservatives.

The role of preservatives is mainly to maintain the freshness of products and to avoid bacterial and fungal infections.

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 medicines and can prolong the shelf life of other active ingredients under high temperature conditions.

Used as pharmaceuticals and intermediates in organic synthesis

It is mainly used to synthesize α-bromo-p-hydroxyacetophenone, which is an important intermediate in the synthesis of selective B1 receptor blocker-atenolol.

P-Hydroxyacetophenone, since its particle contains hydroxyl as well as ketone teams on the benzene ring, is often used as an intermediate in organic synthesis to respond with various other compounds to synthesize several important materials.

Para-hydroxyacetophenone itself is a choleretic drug. It is often used as an auxiliary drug for the treatment of cholecystitis and acute and chronic jaundice hepatitis, but the application must follow the doctor’s advice.

used as a spice

In addition, p-hydroxyacetophenone is also a raw material for fine chemical synthesis, which is mostly used in the synthesis of fragrances.
