Description

3,7,11,15-Tetramethyl-1,6,10,14-Hexadecatetraen-3-Ol CAS NO 68931-30-6 is a high-purity, long-chain isoprenoid alcohol, also known as a diterpene alcohol, which serves as a critical intermediate in the synthesis of complex natural products and fine chemicals. Its value lies in its precise molecular structure, which is essential for producing high-value compounds in the pharmaceutical and fragrance industries. This product is primarily needed by R&D laboratories, fine chemical manufacturers, and producers of specialty ingredients for cosmetics and agrochemicals seeking reliable, high-quality building blocks.

Application

• Pharmaceutical Intermediate: A key chiral building block for the synthesis of complex diterpenoids, vitamins (e.g., Vitamin E, K), and other bioactive molecules.
• Fragrance & Flavor Synthesis: Used in the production of high-value aroma chemicals and natural fragrance compounds due to its isoprenoid backbone.
• Agrochemical Research: Serves as a precursor in developing novel plant growth regulators and insect pheromones.
• Cosmetic Ingredients: Employed in the synthesis of specialty esters and other compounds for advanced skincare formulations.
• Organic Synthesis & Catalysis: A valuable substrate in academic and industrial research for studying terpene cyclization and other stereoselective reactions.
• Nutritional Supplements: Potential intermediate in the manufacture of certain nutraceuticals and coenzyme Q10 analogs.

Quality Control

Our 3,7,11,15-Tetramethyl-1,6,10,14-Hexadecatetraen-3-Ol is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity and isomer content, GC for residual solvents, and spectroscopic identification (IR, NMR), to ensure it meets precise customer specifications. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are available upon request for full traceability and quality assurance.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at controlled room temperature (15-25°C) in a cool, dry, and well-ventilated place. This product is easily oxidized and light-sensitive; prolonged exposure to air or light should be avoided to maintain stability and purity.
