ALPHA-PINENE Usage And Synthesis

Definition

ChEBI: (-)-alpha-pinene is an alpha-pinene. It is an enantiomer of a (+)-alpha-pinene.

Contact allergens

Alpha-pinene is the major constituent of turpentine (about 80%). It exists in levogyre form in European turpentine and in dextrogyre form in turpentine found in North-Americans. Sensitization occurs mainly in painters, polishers, and varnishers, and in those in the perfume and in the ceramics industry.
