3. Key Applications & Chemical Properties

A. Flavor & Fragrance Synthesis

$\alpha$-Pinene is a highly reactive bicyclic monoterpene essential for the fragrance industry.

• Isomerization: It serves as the primary raw material for Camphene. Our high-purity grade ensures high selectivity during isomerization.

• Hydration: Acid-catalyzed hydration yields Terpineol, used widely in lilac and soap fragrances.

• Esterification: Further processing creates high-value esters like Isobornyl Acetate.

B. Pharmaceutical Industry

Used as the starting material for Synthetic Camphor and Borneol.

• Chirality Matters: We can provide specific optical rotation profiles to meet the stereochemical requirements of pharmaceutical synthesis pathways.

C. Solvents & Resins

• Solvency Power: High Kauri-Butanol (KB) value ensures excellent solubility for alkyd and phenolic resins.

• Coalescing Agent: With a boiling point of 156°C, it acts as an effective coalescing agent in coatings, improving leveling and preventing blushing.

4. Packaging & Logistics

To maintain chemical activity and prevent oxidation, we use industrial-standard anti-oxidation packaging.

• Galvanized Iron Drums: 175 kg / Drum (Net Weight).

• ISO Tank: 20 – 21 MT / Tank (Bulk shipment).

• Storage: Store in a cool, dry, and well-ventilated warehouse. Keep away from fire and heat sources (Max temp < 30°C). Keep container tightly closed to prevent contact with oxidizers.

5. Quality Assurance

Our facility utilizes advanced rectification towers and online GC monitoring.

• Batch Traceability: Every shipment includes a specific COA and retained sample.

• Impurity Control: We strictly monitor $\beta$-Pinene and other terpene isomer levels to ensure predictable reaction kinetics for our customers.
