Description

Permethylsorbitol is a fully methylated derivative of sorbitol, a versatile polyol. This compound is valued for its role as a key intermediate in the synthesis of specialty chemicals and as a building block for advanced materials. It is particularly relevant for industries focused on polymer chemistry, surfactants, and pharmaceutical excipients. Its defined structure and consistent reactivity make it a reliable choice for research and industrial applications requiring precise chemical modifications.

Application

• Polymer Chemistry: Acts as a monomer or cross-linking agent in the synthesis of specialty polyethers and resins.
• Surfactant & Emulsifier Production: Serves as a hydrophobic intermediate for creating non-ionic surfactants with specific solubility profiles.
• Pharmaceutical Excipients: Used in the development of controlled-release formulations and as a component in tablet coatings.
• Chemical Synthesis: Functions as a protected intermediate or a chiral building block in organic synthesis for agrochemicals and fine chemicals.
• Lubricant & Fuel Additives: Employed in the formulation of synthetic lubricants and fuel system icing inhibitors.
• Cosmetic Ingredients: Utilized in the production of emollients and texture modifiers for personal care products.

Quality Control

Our Permethylsorbitol is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including chromatographic purity assays and identity confirmation, to ensure it meets high-purity standards suitable for research and industrial use. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product quality and stability.
