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.
