Description

(+)-β-Pinene CAS NO 19902-08-0 is a high-purity, naturally derived monoterpene enantiomer prized for its distinct woody-pine aroma and versatile chemical reactivity. This compound is a critical building block and fragrance ingredient, valued for its role in synthesizing fine chemicals, flavors, and advanced materials. It is essential for manufacturers in the fragrance, flavor, pharmaceutical intermediate, and agrochemical sectors seeking a reliable and consistent chiral starting material.

Application

• Fragrance & Flavor Industry: A key natural ingredient and aroma chemical for creating fresh, piney, and woody top notes in perfumes, cosmetics, air fresheners, and household cleaners.
• Chemical Synthesis: Serves as a chiral precursor and intermediate in the production of fine chemicals, pharmaceuticals (e.g., vitamins, aroma chemicals like linalool), and specialty polymers.
• Agrochemical Formulations: Used as a solvent or active carrier in pesticides and herbicides, and as a starting material for synthesizing certain insect pheromones.
• Industrial Solvents & Cleaners: Employed as a bio-based, high-performance solvent in formulations for resins, adhesives, and industrial degreasers.
• Research & Development: A standard reagent in organic chemistry laboratories for studying terpene chemistry, asymmetric synthesis, and natural product isolation.
