What is 1,1,3-Trichloroacetone?

Description

1,1,3-Trichloroacetone is direct-acting mutagens in the Ames/Salmonella assay. It is precursor for the generation of 1,3-dihalo oxyallyl intermediates, which undergo [4 + 3] cycloadditions with a host of 1,3-diene systems.

Chemical properties

Light yellow transparent liquid

The Uses of 1,1,3-Trichloroacetone

1,1,3-Trichloroacetone was used in base-induced solvolyses of [3.2.1]Bicyclic α,α′-dichloro ketones.

The Uses of 1,1,3-Trichloroacetone

1,1,3-Trichloroacetone is a reagent used to synthesize chlorinated 5-hydroxy-4-methyl-2(5H)-furanones and mucochloric acid. In addition, it can also be used to synthesize (+)-Phorbol. Phorbol derivatives are important for biomedical research and capable of stimulating T-cell activation, proliferation and cytokine production.
