Description

Alpha-pinene is a monoterpene that occurs widely in nature, best known for its sharp pine scent. It's a major constituent of gum turpentine and shows up in more than 400 natural essential oils, including pine, fir, eucalyptus, rosemary, sage and frankincense oils.

Commercial-grade alpha-pinene is produced by fractionally distilling gum turpentine, a process that keeps its quality and stability consistent from batch to batch.

This is the levorotatory (-ve) form — (1S)-(-)-α-pinene — used in flavor and fragrance work mainly as a building block for terpineol, linalool and sandalwood-type fragrance materials, and occasionally as a flavoring agent in daily chemical products at under 2% concentration.

Application & Uses

Key Aroma Chemical Intermediate: Serves as a key starting material in flavor and fragrance manufacturing, used extensively to synthesise valuable aroma chemicals such as terpineol, linalool, camphor and sandalwood-type fragrance materials.
Direct Application in Flavours & Fragrances: Contributes fresh, woody, pine-needle notes when incorporated directly into fragrance formulations, and is also used at under 2% as a flavoring or enhancing agent in daily chemical products.
Other Industrial Applications: Also functions as a chemical intermediate for resins, adhesives and solvents, and within pharmaceutical manufacturing — for example, in preparing terpene maleic anhydride (TMA).

FAQ

What is Alpha Pinene and where is it commonly found?

Alpha-pinene is a naturally occurring monoterpene with a sharp pine scent. It's a major constituent of gum turpentine and occurs in more than 400 natural essential oils, including pine, fir, eucalyptus, rosemary, sage and frankincense.

What are the main industrial applications of Alpha Pinene?

It serves as a key starting material in flavor and fragrance manufacturing (synthesizing terpineol, linalool, camphor and sandalwood-type fragrances), as a direct fragrance component in daily chemical products, and as a chemical intermediate for resins, adhesives, solvents and pharmaceutical products such as terpene maleic anhydride (TMA).

What is the difference between Alpha Pinene and Beta Pinene?

Both are pinene isomers found in turpentine oil, but they differ in downstream use — alpha-pinene is used mainly for terpineol, linalool and camphor-type fragrance synthesis, while beta-pinene is the preferred feedstock for synthetic myrcene and its derivatives such as geraniol and nerol.

What are the physical and chemical properties of Alpha Pinene?

It's a colorless to pale yellow liquid with a woody, pine-like odor, molecular formula C10H16, molecular weight 136.24. Commercial grades run 95% or 98% purity, with a refractive index of about 1.464–1.474 and relative density of 0.855–0.870.

What industries use Alpha Pinene as a raw material?

It's used across fragrance and flavor manufacturing, daily chemicals, resin and adhesive production, and pharmaceutical synthesis.

What is the typical purity of industrial-grade Alpha Pinene?

Commercial-grade alpha-pinene is typically supplied at 95% or 98% minimum purity, available in both dextrorotatory (+ve) and levorotatory (-ve) optical forms.

How is Alpha Pinene obtained from pine-based raw materials?

It's produced by fractionally distilling gum turpentine, a process that keeps its quality and stability consistent from batch to batch.

How should Alpha Pinene be stored and handled?

Store it in a cool, dry, well-ventilated area away from light and heat sources; it's a flammable liquid, so keep it away from sparks, open flames and incompatible materials, in tightly closed, clearly labelled containers, ideally in a dedicated safety cabinet.

What factors should buyers consider when sourcing Alpha Pinene?

Check the purity grade (95% vs 98%), the optical form required (dextro vs levo) for the intended synthesis, consistent refractive index and density specs, and reliable supply for continuous fragrance or resin production.

Is Alpha Pinene used in fragrances, flavors, and chemical synthesis?

Yes — it's a foundational raw material across all three: fragrance and flavor compounding (via terpineol, linalool and camphor synthesis) and broader chemical synthesis for resins, adhesives and pharmaceutical intermediates.

What is the difference between Alpha Pinene 95%, 98%, +ve (Dextro) and -ve (Leavo)?

The percentage is the minimum alpha-pinene assay by GC: 98% grades are used for high-purity fragrance and chemical synthesis, and 95% grades for general industrial use. The +ve / -ve sign is the optical rotation: +ve (dextrorotatory, "Dextro") and -ve (levorotatory, "Leavo") alpha-pinene are mirror-image forms from different turpentine sources, chosen to match a required chirality or natural profile. "30-35" specifies an optical-rotation band within the 95% grade.

Who supplies Alpha Pinene 95-ve (Leavo) in bulk?

Himalaya Terpenes Pvt. Ltd. (Mumbai, India) supplies Alpha Pinene 95-ve (Leavo) in bulk, in drums, bags, IBCs or ISO tanks depending on the grade, for domestic and export orders. The company is an ISO 9001:2015-certified pine-chemical manufacturer operating since 1971.
