alpha-Pinene

95%

alpha-Pinene is an important monoterpene naturally occurring in nature, known for its distinctive pine scent. It is a primary component of Gum turpentine and is widely found in over 400 types of natural essential oils, including those from pine, fir, eucalyptus, rosemary, sage, and frankincense.

Industrially, high-purity alpha-Pinene is primarily extracted through the fractional distillation of gum turpentine, ensuring its quality and stability.

In the flavor and fragrance industry, alpha-Pinene is primarily used to synthesize compounds such as Terpineol, Linalool, and other sandalwood fragrances. It is also used as a flavoring agent in daily chemicals, with a typical content of less than 2%.

Application & Uses

  • Key Aroma Chemical Intermediate: alpha-Pinene serves as a crucial starting material in the flavour and fragrance industry, extensively used for the synthesis of various valuable aroma chemicals such as Terpineol, Linalool, Camphor, and for creating sandalwood-type fragrances.
  • Direct Application in Flavours & Fragrances: As a unique aromatic component, it is directly incorporated into fragrance formulations to impart fresh, woody, and pine-needle-like notes. In daily chemicals, it is also commonly used as a flavouring or enhancing agent, typically at concentrations of less than 2%.
  • Other Industrial Applications: alpha-Pinene also acts as an important chemical intermediate in the synthesis of resins, adhesives, solvents, and within the pharmaceutical sector, for instance, it can be used in the preparation of terpene maleic anhydride (TMA).
