| | 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 | 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. | | Uses | Commonly used building block in aldol condensation reactions. | | Definition | ChEBI: 2,2-dimethylpropanal is a member of the class of propanals that is propanal substituted by two methyl groups at position 2. It is a member of propanals and a 2-methyl-branched fatty aldehyde. | | References | Ho, Tse Lok, et al. Pivaldehyde. Fieser and Fieser's Reagents for Organic Synthesis. John Wiley & Sons, Inc. 2006.
