Chemical Properties

Clear colorless to yellow liquid

Uses

1,1-Dimethylpropargylamine is used as an organic chemical synthesis intermediate.

Hazard

Moderately toxic by ingestion. A moderate eye irritant.

Purification Methods

Dissolve the amine in Et2O, dry over anhydrous K2CO3, filter, evaporate and distil (preferably under N2). Store it away from CO2. The hydrochloride [2978-59-8] has m 234o (from EtOH/Et2O). The benzoyl derivative has m 152-153o (from EtOH). [Hennion & Teach J Am Chem Soc 75 1653 1953, Hennion & DiGiovanna J Org Chem 30 2645 1965.]
