o-phenylphenol, OPP

Solubility: Easily soluble in sodium hydroxide solution, ethanol, acetone and other organic solvents, slightly soluble in water.

Application:

1. It is a deoxyribonuclease (DNase) inhibitor with high herbicidal activity, high-efficiency and broad-spectrum sterilization, anti-mildew, disinfection and anti-corrosion capabilities, and low toxicity and tasteless. In foreign countries, this product and its sodium salt have been widely used in the storage of fruits, vegetables, and meat for anti-corrosion and anti-mold, and have a wide range of uses. As well as disinfectants and anti-mold agents for fibers, protein materials and other materials (wood, fabrics, paper, adhesives and leather, etc.). When the concentration is 0.005% ~ 0.006%, it shows a very good bactericidal effect, which is many times greater than that of the lower esters of benzoic acid and p-hydroxybenzoic acid. It is also a commonly used preservative in cosmetics (the dosage is generally 0.05% ~ 0.25%) .

2. It can be used for hydrophobic synthetic fibers, such as the carrier and dye intermediate of polyvinyl chloride and polyester carrier dyeing method; it can also be used as heat stabilizer and surfactant for plastics. It is mainly used in the industry to prepare oil-soluble o-phenylphenol formaldehyde resin. This resin is the starting material for clear coats with excellent water and alkali stability.

3. It is also used as a triose analysis and detection reagent in bioanalytical chemistry; in addition, this product can also be used as an auxiliary agent in the rubber industry and photographic chemicals.
