Hazard Information

Description

Methyl trimethylacetate(598-98-1) is a colorless liquid, the methyl ester of pivalic acid. The ester is well known for being resistant to hydrolysis to the parent acid. Hydrolysis can be effected with a solution of trimethylsilyl iodide in hot acetonitrile followed by aqueous workup. It is used to make vinyl chloride resins, as a chemical intermediate, and in adhesives, lubricants, greases, and fuel additives.

Chemical Properties

CLEAR COLOURLESS LIQUID

Uses

Methyl Pivalate(598-98-1) is a useful chemical reagent for the preparation of esters and transesterification.

Application

Methyl trimethylacetate(598-98-1) is used in the manufacture of vinyl chloride resins, as a chemical intermediate in the preparation of Ruxolitinib, and in adhesives, lubricants, greases and fuel additives. It is also utilised as a material for lithium-ion batteries or as a raw material for organic synthesis.

Hazard

Methyl trimethylacetate is a highly flammable liquid and is harmful if swallowed. Prolonged exposure may lead to acute solvent syndrome, an occupational disease.
