Pyrrole-2-carbonitrile - Introduction
Pyrrole-2-carbonitrile, the chemical formula is C5H4N2, which is an important organic compound.
nature: Pyrrole-2-carbonitrile is a colorless liquid with a similar aromatic smell at room temperature. It is almost insoluble in water, but soluble in many organic solvents such as ethanol, ether and benzene. It has a certain corrosivity.
Uses: Pyrrole-2-carbonitrile is a commonly used synthetic compound that can be used to prepare other organic compounds. It is often used as an intermediate in the fields of medicine and pesticide. In addition, Pyrrole-2-carbonitrile can also be used in the preparation of organic electronic devices.
Preparation method: The Pyrrole-2-carbonitrile is generally prepared by reacting pyrrole with a cyanide compound. The common preparation method is to react pyrrole with sodium cyanide, and then treat it with acid to obtain Pyrrole-2-carbonitrile.
Safety Information: Pyrrole-2-carbonitrile is irritating at high concentrations and may be harmful to the eyes, skin and respiratory system. Care should be taken to avoid contact with skin and eyes and maintain good ventilation during use. Wear appropriate protective equipment such as gloves, goggles and respirators when necessary. If inhaled or exposed to large amounts of Pyrrole-2-carbonitrile, seek medical attention immediately.
