Description

β-Pinene is a naturally occurring bicyclic monoterpene, a key constituent of turpentine and various essential oils. This versatile organic compound is highly valued for its fresh, woody-pine aroma and its role as a crucial chemical intermediate in industrial synthesis. It serves as a fundamental building block for the production of flavors, fragrances, resins, and fine chemicals. Key industries that utilize β-Pinene include flavor & fragrance, agrochemicals, and polymer manufacturing.

Application

• Flavor and Fragrance (F&F) Industry: A primary raw material for creating fresh, pine, and woody notes in perfumes, colognes, air fresheners, and household cleaning products.
• Synthetic Chemistry: Acts as a key chiral starting material and intermediate in the synthesis of fine chemicals, aroma chemicals like linalool and geraniol, and pharmaceutical precursors.
• Agrochemicals: Used in the formulation of certain pesticides and as a solvent or co-formulant in agricultural applications.
• Resin and Polymer Production: Serves as a monomer or modifier in the synthesis of specialty resins, tackifiers, and polymers.
• Industrial Solvents: Employed as a high-purity solvent in specific industrial cleaning and formulation processes.
• Adhesives and Inks: Functions as a solvent and reactivity modifier in the formulation of certain adhesives and printing inks.

Quality Control

Our β-Pinene is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive quality assurance, with product specifications tailored to meet the requirements of the flavor & fragrance and fine chemical industries. Certificates of Analysis (COA) detailing purity, enantiomeric ratio, and impurity profiles are available for every batch upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and open flames. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and maintain product integrity. Recommended storage temperature is between 15°C and 25°C.
