alpha Cedrene
alpha-Cedrene 90% is a high-purity sesquiterpene, naturally found in cedarwood oil, often alongside Beta Cedrene and Thujopsene. This product appears as a light yellow transparent liquid, exuding a distinctive woody aroma. Industrial grade α-Cedrene is obtained through the meticulous separation of cedar oil, removal of “cedar brains”, and subsequent fractionation of the remaining sesquiterpene-rich components. In China, this product typically boasts an α-Cedrene content of over 85%, ensuring its exceptional quality.
It is widely used in fragrance formulation and the synthesis of more valuable aromatic substances, such as acetyl cedrene, cedryl ketone, etc.
