Description

2,5,8,11-Tetramethyl-3,6,9,12-Tetraoxahexadecan-1-Ol is a high-purity, branched polyether alcohol with a defined molecular structure. This compound is valued for its role as a versatile intermediate and functional additive, offering properties like hydrophilicity and surfactant behavior. It is essential for manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries seeking to modify solubility, stability, or surface characteristics in their formulations.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs to enhance water solubility and bioavailability.
• Polymer & Resin Modifier: Acts as a co-monomer or plasticizer in specialty polymers, polyurethanes, and epoxy resins to impart flexibility and hydrophilicity.
• Agrochemical Formulations: Serves as a non-ionic surfactant or adjuvant in pesticides and herbicides to improve emulsification, spreading, and penetration.
• Personal Care & Cosmetics: Functions as a humectant, emollient, or viscosity modifier in creams, lotions, and hair care products.
• Lubricant & Fuel Additive: Employed as a detergent or dispersant additive in synthetic lubricants and fuels to prevent deposit formation.
• Chemical Synthesis: A key building block for creating complex polyether structures, crown ether analogs, and other specialty chemicals.

Quality Control

Our 2,5,8,11-Tetramethyl-3,6,9,12-Tetraoxahexadecan-1-Ol is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing specific batch results are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at 15-25°C. This material is hygroscopic (moisture-sensitive) and easily oxidized; for long-term storage, consider using an inert atmosphere (e.g., nitrogen or argon) to maintain product integrity.
