Product Description

Property

CAS No.: 71-55-6 Formula: C2H3Cl3 Molecular Weight: 133.40400

Description

The organic compound 1,1,1-trichloroethane, also known as methyl chloroform, is a chloroalkane. This colourless, sweet-smelling liquid was once produced industrially in large quantities for use as a solvent. It is regulated by the Montreal Protocol as an ozone-depleting substance and its use is being rapidly phased out.
