(+)-alpha-Pinene is employed in the preparation of chiral hydroboration reagents. It is a bronchodilator in humans. α-Pinene is an anti-inflammatory and used as a broad-spectrum antibiotic.It exhibits activity as an acetylcholinesterase inhibitor, aiding memory. It is a biosynthetic base for CB2 ligands, such as HU-308.

Forms a chiral adduct with diborane, useful for asymmetric hydroborations with high optical yields: J. Am. Chem. Soc., 99, 5514 (1977).
