Pyrazole is an important organic synthesis intermediate, which needs to pay attention to the following aspects in the use process:
1. Prevent skin contact: pyrazole has strong irritation and toxicity, it is necessary to avoid skin contact or inhalation when using, and pay attention to personal protective measures, such as wearing gloves, masks, goggles and other protective equipment.
2. Prevent inhalation: pyrazole has a heavy irritating smell, easy to inhale respiratory tract cause irritation and injury, so should avoid operating pyrazole in poor air or confined Spaces.
3. Avoid contact with water, acid, alkali: pyrazole is susceptible to moisture absorption, easy to decompose in water, and is not resistant to acid and alkali, so it should avoid long-term contact with water, acid, alkali and other substances.
4. Storage conditions: pyrazole should be kept away from direct sunlight during storage, stored in a cool, dry and ventilated place, and stored separately from other organic matter to avoid fire or explosion and other dangers.
5. Operation skills: The melting point of pyrazole is high, and it needs to be heated and stirred when in use to ensure its complete melting and reaction.
In short, when using pyrazole, it is necessary to pay attention to personal protective measures, operating skills, storage conditions, etc., to ensure the safety and stability of the use process.
