Introduction
2-methyl-3-nitrotrifluorotoluene is an organic compound. The following is an introduction to its nature, use, manufacturing methods and safety information:
Quality:
- Appearance: White crystalline solid
- Solubility: Soluble in organic solvents such as ether, methanol and dimethyl sulfoxide
Use:
- It can also be used as a reagent in organic synthesis reactions, such as a source of nitrous acid and sulfur dioxide.
Method:
- MTF is usually prepared by nitrification and fluorine substitution of benzoic acid. First, benzoic acid is nitrified to obtain 2-nitrobenzoic acid, and then the carboxyl group in nitrobenzoic acid is substituted into trifluoromethyl group through fluorine gas substitution reaction.
Safety Information:
- MTF has certain toxicity and may cause harm to the human body, so it is necessary to pay attention to safety when using and operating.
- Contact with skin, inhalation, or accidental ingestion may cause irritation and injury, and appropriate precautions should be taken if necessary.
- Avoid contact with strong oxidizing agents and combustibles to prevent fire or explosion.
- When using and storing, follow the relevant safety operating procedures.
