Thourea, (4-chlorophenyl)- (9CI) - Introduction
4-Chlorophenylthiourea(4-Chlorophenylthiourea) is an organic compound with the chemical formula C7H6ClN3S. It is a white crystalline solid, sparingly soluble in water and soluble in organic solvents such as chloroform, ethanol and ether.
4-Chlorophenylthiourea can be used as an intermediate in medicine and agriculture. It can be used as a raw material for the synthesis of drugs and pesticides. In addition, it can also be used as a starting material for biologically active compounds in some research fields.
Preparation of 4-Chlorophenylthiourea can be obtained by reaction of phenyl isocyanate and thiourea. The phenylisocyanate is first reacted with thiourea by heating in an organic solvent and then purified by crystallization to give the product.
For chemical laboratory operators, some safety precautions need to be paid attention to when using 4-Chlorophenylthiourea. It may be irritating to the eyes, skin and respiratory system. Appropriate personal protective measures should be taken during operation, such as wearing protective glasses, gloves and protective clothing. At the same time, it should be ensured that the operation is carried out under good ventilation conditions to avoid inhalation of its vapor or dust. If accidental contact or inhalation, should immediately rinse with plenty of water, and timely medical treatment.
