Description

3,7,11,15-Tetramethylhexadecan-1-Ol CAS NO 645-72-7 is a high-purity, long-chain isoprenoid alcohol, also known as phytol. This compound serves as a critical intermediate and building block in the synthesis of valuable fine chemicals and natural product analogs. It is essential for manufacturers in the fragrance, flavor, pharmaceutical, and specialty chemical industries seeking reliable, high-quality raw materials for complex syntheses.

Application

• Fragrance and Flavor Industry: A key intermediate in the synthesis of vitamins E and K1, which are used as aroma chemicals and nutritional additives.
• Pharmaceutical Intermediates: Serves as a crucial chiral building block for the production of terpenoid-based active pharmaceutical ingredients (APIs).
• Specialty Chemical Synthesis: Used in the manufacture of surfactants, plasticizers, and other fine chemicals that benefit from its long, branched hydrocarbon chain.
• Research and Development: A valuable standard and starting material in organic chemistry research, particularly in studies involving isoprenoids and terpenes.
• Cosmetic Ingredients: Employed as a precursor for the synthesis of esters used in skincare and cosmetic formulations for their emollient properties.

Quality Control

Our 3,7,11,15-Tetramethylhexadecan-1-Ol is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including chromatographic purity assays and identity confirmation, to ensure it meets exacting standards for industrial and research use. A Certificate of Analysis (COA) detailing purity, physical properties, and test results is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen) in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its sensitivity to oxidation, containers should be kept tightly sealed when not in use to minimize exposure to air.
