168267-99-0 - Introduction
acid, chemical formula C7H7BF3O2, is an organic compound. The following is a description of the nature, use, preparation and safety information of the polymer acid:
Nature:
1. Appearance: acid is a colorless crystalline solid.
2. Melting Point: about 120-124 degrees Celsius.
3. Solubility: acid has low solubility in water, but it is soluble in many organic solvents.
Use:
1. acid is commonly used as a reagent in organic synthesis. It can be used as an important intermediate of Phenylboronic acid compounds, and participate in the preparation process of drugs, pesticides and synthetic modified polymers.
2. acid can also be used as a catalyst in some organic reactions, such as C- C bond formation and fluorination of aromatic compounds.
Method:
A commonly used method for preparing acid is obtained by the fluorination reaction of p-methylphenylboronic acid. The specific method can refer to the detailed procedures in the organic synthesis handbook or related literature.
Safety Information:
1. acid has a certain irritation, avoid contact with skin and eyes. Wear appropriate protective equipment such as gloves and goggles during use.
2. Avoid inhaling acid dust and gas to avoid discomfort. Maintain a well-ventilated laboratory environment.
3. In use, storage and handling, please follow the relevant safety procedures, avoid contact with flammable substances, oxidants and strong acids.
