Product Description

Common Name:4-Hydroxybenzoic acid
CAS: 99-96-7
Molecular Formula: C₇H₆O₃
Molecular Structure: 



Parahydroxybenzoic acid is an organic compound with the molecular formula C7H6O3. The pure product is colorless fine crystals or crystalline powder. In addition to being effective against fungi, parabens also have stronger antibacterial properties than benzoic acid and sorbic acid because of their phenolic hydroxyl structure. The characteristic of parabens is that their toxicity is lower than that of benzoic acid, and their antibacterial effect has nothing to do with pH value. However, due to its relatively low water solubility and special odor, its application in food preservation is limited. In addition to being used as a preservative in food, it is mostly used as a preservative in drugs and cosmetics.

use
Parahydroxybenzoic acid is a widely used raw material for organic synthesis, especially its esters, including methyl parahydroxybenzoate (paraben A), ethyl parahydroxybenzoate (paraben B), propyl ester, butyl ester, and isopropyl ester , isobutyl ester, can be used as a food additive, used in soy sauce, vinegar, refreshing drinks (except soda), fruit flavorings, fruits and vegetables, pickled products, etc. It is also widely used in the antiseptic and anti-mildew properties of food, cosmetics, and medicine. agents and fungicides, etc. Parahydroxybenzoic acid is also used as an intermediate for dyes and pesticides. In pesticides, it is used to synthesize organophosphorus pesticides GYAP and CYP; in the dye industry, it is used to synthesize color developers of heat-sensitive dyes; it can also be used in color films and synthetic oil-soluble couplers "538" and nylon 12 Raw materials for the production of plasticizers. In addition, it is also used in liquid crystal polymers and plastics.
As a preservative and bactericide. Pharmacological experiments show that it has a significant protective effect on cobra poisoning in mice. This product can inhibit the growth of mold and react with alcohols such as ethanol, propanol, butanol and other alcohols to form various esters, which are excellent preservatives. This product can also be used as a preservative and insecticide in dyeing, organic synthesis industry and other fields.
