Used as a strong base and nucleophile in organic synthesis, particularly for alkyne preparation. It reacts with alkyl halides to form substituted acetylenes or adds to carbonyl compounds like aldehydes and ketones to produce propargyl alcohols, enabling carbon-carbon bond formation. Commonly applied in pharmaceutical and agrochemical industries for building complex molecules. Its suspension form enhances handling and reactivity control in non-aqueous solvents like liquid ammonia or ethers. Requires careful temperature management due to high reactivity and moisture sensitivity.
