Tetrachloromethane







General Information:


Structure:



CAS Number: 56-23-5

Due to its symmetrical structure, carbon tetrachloride (CCl4) is non-polar. Its non-polar nature makes it a suitable solvent for dissolving non-polar compounds. Carbon tetrachloride is convenient as a solvent for NMR because it contains no protons, however, its poor dissolving power limits its usefulness.




Common Uses:


Solvent in benzylic brominations





Safety:


Carbon tetrachloride is toxic to the central nervous system. It is not flammable, and actually at one time was used in fire extinguishers.
