application | organic fluorine compounds have significantly higher chemical stability and physiological activity than other compounds, and have strong fat solubility and hydrophobicity. the verification shows that fluorine-containing medicines and pesticides have lower toxicity, higher efficacy and stronger metabolic ability than other products, so they are widely used in the manufacturing of medicines and pesticides and other fields. 3, 5-difluorophenol is an off-white crystal with a melting point of 51~55 ℃. It is mostly used in the synthesis of liquid crystal materials, anti-mold agents, etc., and is also used in the synthesis of dyes, plastics and rubber additives. It is an important medicine, pesticide, liquid crystal material intermediates, and the market is in demand. |
uses | pharmaceutical pesticide intermediates. |
