If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek Medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medi- cal attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.

UN3276 Nitriles, liquid, toxic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required, Potential Inhalation Hazard (Special Provision 5).

Oxidizing agents, such as perchlorates, peroxides, and permanganates. Nitriles may polymerize in the presence of metals and some metal compounds. They are incompatible with acids; mixing nitriles with strong oxidizing acids can lead to extremely violent reactions. Nitriles are generally incompatible with other oxidizing agents such as peroxides and epoxides. The combination of bases and nitriles can produce hydrogen cyanide. Nitriles are hydrolyzed in both aqueous acid and base to give car- boxylic acids (or salts of carboxylic acids). These reactions generate heat. Peroxides convert nitriles to amides. Nitriles can react vigorously with reducing agents. Acetonitrile and propionitrile are soluble in water, but nitriles higher than propionitrile have low aqueous solubility. They are also insoluble in aqueous acids .

The cyanopyridines are as follows:2-cyano-: A white to tan liquid or solid with an almondodor. Boiling point=about 213℃; Freezing/Meltingpoint=27℃; Flash point=89℃.3-cyano-: A colorless liquid or gray crystalline solid.Molecular weight=104.12; Boiling point=83-84℃;Freezing/Melting point=47-49℃. Hazard Identification(based on NFPA-704 M Rating System): Health 3,Flammability 3, Reactivity 0. Soluble in water.4-cyano-: A beige solid. Freezing/Melting point=75.8℃

The cyanopyridines are as follows: 2-cyano-: A white to tan liquid or solid. Almond odor. Boiling point=2213℃ ; freezing/melting point=27℃ ; flash point=89℃ . 3-cyano-: a colorless liquid or gray crystal- line solid.

white to brown low melting crystalline solid

2-Cyanopyridine is a cyano substituted pyridine. 2-Cyanopyridine is a related compound of nicotine and is a component of tobacco smoke condensate.

ChEBI: A cyanopyridine carrying the cyano group at position 2.
