What is Dichloropentane?

Plain description, key identifiers and synonyms

Dichloropentane is a clear colorless to yellow liquid. Less dense than water and insoluble in water. Hence floats on water. Vapors are heavier than air. Used as a solvent for oil, greases, rubber resins, for degreasing metals and as an insecticide and soil fumigant.
