2740-81-0 - Introduction
2-Chlorophenyl isothiocyanate, also known as 2-Chlorophenyl isothiocyanate, with the chemical formula C7H4ClNS, is an organic compound. The following is a description of its nature, use, preparation and safety information:
Nature:
2-Chlorophenyl isothiocyanate is a colorless to slightly yellow liquid with a pungent odor. It can be dissolved in some organic solvents, such as methanol, ethanol and dimethylformamide. It is highly volatile in the air, so you need to pay attention to ventilation conditions when storing and using.
Use:
2-Chlorophenyl isothiocyanate is mainly used in organic synthesis reactions. It is a commonly used reagent and is widely used in the synthesis of pesticides, pharmaceuticals and other organic compounds. It is highly reactive and can chemically react with other functional groups by nucleophilic substitution, condensation reaction, interconversion reaction, and the like.
Method:
Generally, 2-Chlorophenyl isothiocyanate can be prepared by reacting 2-chloroaniline with thiocyanate. During the reaction, it is necessary to control the temperature and reaction time, and at the same time, a suitable solvent and catalyst are needed to promote the reaction and improve the yield.
Safety Information:
2-Chlorophenyl isothiocyanate is an organic compound that is irritating and corrosive. Pay attention to safety measures during operation and storage, and avoid direct contact with skin, eyes and respiratory tract. Wear suitable personal protective equipment such as protective gloves, goggles and masks and ensure that the experiment is carried out in a well-ventilated environment. In case of accidental contact, rinse immediately with plenty of water and seek medical help.
