Description

(1S)-(1)-β-Pinene CAS NO 18172-67-3 is a high-purity, natural monoterpene enantiomer widely valued for its distinct woody-pine aroma and chiral specificity. This compound is essential for creating authentic, high-value fragrance profiles and serving as a chiral building block in advanced organic synthesis. It is a critical raw material for flavor and fragrance houses, aroma chemical producers, and fine chemical manufacturers targeting the pharmaceutical and agrochemical sectors.

Application

• Fragrance & Flavor Ingredient: A key component in perfumery for creating fresh, woody, and pine-like top notes in fine fragrances, household cleaners, and air fresheners.
• Aroma Chemical Synthesis: Serves as a premium starting material for the synthesis of other valuable aroma chemicals like linalool, geraniol, and camphor.
• Chiral Intermediate: Utilized in asymmetric synthesis within the pharmaceutical industry to produce enantiomerically pure active pharmaceutical ingredients (APIs).
• Agrochemical Formulations: Employed as a solvent or intermediate in the production of certain pesticides and herbicides.
• Industrial Solvent & Cleaner: Used in specialty formulations for resins, adhesives, and industrial cleaning products due to its solvency properties.
• Research & Development: A standard reagent in organic chemistry research, particularly in studies involving terpene chemistry and stereoselective reactions.

Quality Control

Our (1S)-(1)-β-Pinene is produced and tested under a strict quality management system. Each batch is analyzed to ensure it meets high-purity standards, with key parameters including optical purity (enantiomeric excess) and chemical assay verified by GC and chiral HPLC. A Certificate of Analysis (COA) detailing specific results is provided with every shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and open flame. 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: 2-8°C for long-term stability.
