Aplicaciones

(+)-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.

Notas

Incompatible materials are Strong oxidizing agents. Store in cool place. Keep container tightly closed in a dry and well-ventilated place.
