1736-72-7 - Introduction
4-(Trifluoromethyl)phenylthiourea is an organic compound with the chemical formula C7H4F3N3S. The following is a description of its nature, use, preparation and safety information:
Nature:
4-(Trifluoromethyl)phenylthiourea is a colorless crystal or white powder with a pungent odor. It is stable at room temperature, but may decompose when heated. It is stable under acidic and basic conditions, but may react with oxidants.
Use:
4-(Trifluoromethyl)phenylthiourea is a commonly used pesticide and herbicide that can be used to control weeds in fields, lawns and fruit trees. In addition, it can also be used as a pharmaceutical intermediate, such as the synthesis of some drugs.
Method:
The preparation of 4-(Trifluoromethyl)phenylthiourea is generally carried out by synthetic routes. One of the commonly used synthetic methods is to 4-amino benzoyl chloride as raw material, with trifluoromethyl thionyl chloride reaction to generate 4-(trifluoromethyl) benzoyl chloride, and then with thiourea reaction to prepare the target product.
Safety Information:
4-(Trifluoromethyl)phenylthiourea needs to follow certain safety measures when using and storing. It is irritating, so contact with skin and eyes should be avoided. Wear appropriate protective gloves, glasses and protective mask during operation. Avoid inhaling its dust or vapor of the solution, and ensure that it is operated in a well-ventilated place. When leakage or accidental contact occurs, it should be removed in time and corresponding disposal measures should be taken. During storage, it should be kept in a fire-proof and explosion-proof container, away from direct sunlight and high temperature.
