Description

2,11-Dimethyl-2,11-Dodecanediol is a high-purity, symmetrical long-chain diol with unique steric properties due to its geminal dimethyl substitution. This compound matters as a versatile chemical intermediate, offering a rigid, hydrophobic backbone that is valuable for synthesizing specialized polymers, surfactants, and fine chemicals. Industries requiring high-performance lubricants, advanced polymer additives, and specialty surfactants will find this diol essential for developing products with enhanced thermal stability and tailored solubility profiles.

Application

• Polymer Synthesis: Acts as a chain extender or monomer for producing polyesters, polyurethanes, and polycarbonates with modified crystallinity and mechanical properties.
• Lubricant & Fuel Additives: Serves as a precursor for synthesizing ester-based lubricants and viscosity index improvers that perform under high-temperature conditions.
• Surfactants & Emulsifiers: Used to create non-ionic surfactants with specific hydrophilic-lipophilic balance (HLB) values for industrial and agrochemical formulations.
• Pharmaceutical Intermediates: Employed in the synthesis of complex molecules and prodrugs, leveraging its defined stereochemistry and functional groups.
• Cosmetic Ingredients: Functions as a building block for emollients and texture-enhancing agents in personal care products.
• Crosslinking Agent: Utilized in coatings, adhesives, and sealants to improve network density and chemical resistance.
• Chemical Research: A valuable standard and reagent in organic synthesis and material science research for studying steric effects.

Quality Control

Our 2,11-Dimethyl-2,11-Dodecanediol is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high chemical purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to guarantee compliance with your specifications and industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled 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. Keep away from strong oxidizing agents.
