Description

Dihydroterpineol CAS NO 21129-27-1 is a high-purity, saturated terpene alcohol derived from pine oil, valued for its mild, pleasant, and persistent woody-floral odor. It serves as a versatile and stable fragrance intermediate and solvent, prized for its excellent fixative properties and resistance to discoloration in formulations. This compound is essential for manufacturers in the fragrance, flavor, and specialty chemical industries seeking reliable, high-quality raw materials.

Application

• Fragrance & Perfumery: A key building block and fixative in fine fragrances, soaps, detergents, and cosmetic products for its stable woody character.
• Flavoring Agent: Used as a flavor ingredient to impart subtle pine and citrus notes in food and beverage applications.
• Industrial Solvent: Acts as a high-boiling point solvent in coatings, inks, and cleaning formulations.
• Chemical Synthesis: An important intermediate in the synthesis of other terpene-based chemicals, pharmaceuticals, and agrochemicals.
• Household & I&I Products: Provides a fresh, clean scent in air fresheners, laundry care products, and industrial cleaning agents.

Quality Control

Our Dihydroterpineol is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including GC, IR, and organoleptic evaluation, to ensure it meets the high standards required for fragrance, flavor, and technical applications. A Certificate of Analysis (COA) detailing purity, identity, and physical properties is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 15-25°C. Keep away from heat, sparks, and open flame. Due to its light-sensitive and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation of quality.
