CAS No. 17788-94-2 is an organic compound known as bis(2-chloroethyl)ether. It is a colorless liquid with a sweet, ether-like odor. This compound is used in the manufacture of dyes, pharmaceuticals, and other chemicals. It is a potential carcinogen, and can be toxic if inhaled or ingested.


Bis(2-chloroethyl)ether is a highly reactive compound and can react with both oxidizing and reducing agents. It is flammable and can produce hazardous fumes if burned. It is soluble in water and insoluble in ethanol, ether and other organic solvents.


Bis(2-chloroethyl)ether is used in the production of dyes, pharmaceuticals, and other chemicals. It is also used as a surfactant in detergents and adhesives, and as an intermediate in the production of other chemicals.


The primary hazard associated with bis(2-chloroethyl)ether is its potential to cause cancer. It is classified as a Group 2B carcinogen by the International Agency for Research on Cancer (IARC) and as a Category 3 carcinogen by the National Toxicology Program (NTP). Exposure to this compound should be minimized, and appropriate protective equipment and clothing should be worn when handling it.


Bis(2-chloroethyl)ether should be stored in a cool, dry, well-ventilated area away from sources of ignition. It should be kept away from strong oxidizing agents and acids. It should be handled in a laboratory environment, and all containers should be labeled clearly and appropriately.
