Pivaldehyde Usage And Synthesis

Description	Trimethylacetaldehyde (also known as Pivaldehyde) is the trimethyl form of acetaldehyde. It is an aldehyde with a sterically bulky R group, the tertiary-butyl group being attached to the carbonyl, >C=O. It is a useful reagent in organic synthesis, pharmaceuticals, agrochemicals and dyestuff. It is useful in streoselective synthesis application as well as in aldol condensation reactions. As a derivative of acetaldehyde, trimethyl acetaldehyde can be used for the production of acetate. It can also be used as the precursor for manufacturing of pyridine derivatives, pentaerythritol, and crotonaldehyde.
Chemical Properties	Clear colorless liquid
Uses	Commonly used building block in aldol condensation reactions.
Uses	Trimethylacetaldehyde is used as a stereoselective synthesis application. It is also used as a building block used in aldol condensation reactions. It is an important raw material and intermediate used in Organic Synthesis, Pharmaceuticals, Agrochemicals and Dyestuff.
