Overview
2,7-Decanediol is a diol compound with the molecular formula C10H22O2. It is commonly used in industrial applications, particularly in polymer chemistry and specialty chemical synthesis. The compound features two hydroxyl groups, which make it a versatile intermediate in organic reactions. Its stable crystalline form and solubility in common organic solvents enhance its utility in various chemical processes. While not as widely used as some other diols, 2,7-decanediol finds niche applications where its specific structure is advantageous.
Physical and Chemical Properties
2,7-Decanediol is a white crystalline solid at room temperature. It is soluble in polar organic solvents such as ethanol, methanol, and acetone but has limited solubility in water. The presence of two hydroxyl groups allows it to participate in reactions typical of diols, such as esterification and etherification. The compound's stability under standard conditions makes it suitable for storage and handling in industrial settings. However, precise data on its melting and boiling points are less commonly reported, and users should consult specific technical datasheets for detailed property information.
Main Applications
2,7-Decanediol is primarily used as a building block in polymer production, where it contributes to the formation of polyesters and polyurethanes. Its diol functionality enables it to act as a chain extender or cross-linking agent in these materials. Additionally, it serves as an intermediate in the synthesis of specialty chemicals, including surfactants and lubricants. Its niche applications often involve scenarios where its specific carbon chain length and hydroxyl group positioning are beneficial.
Safety and Storage
Handling 2,7-decanediol requires standard laboratory safety precautions. Avoid direct contact with skin and eyes, and use protective gloves and goggles. Inhalation of dust or vapors should be prevented by working in a well-ventilated area or using fume hoods. Storage should be in a cool, dry place, away from oxidizing agents and strong acids. Containers must be tightly sealed to prevent moisture absorption and contamination. Proper labeling and adherence to local regulations for chemical storage are essential.
B2B Procurement Guide
When procuring 2,7-decanediol, B2B buyers should prioritize suppliers who provide detailed technical specifications and certificates of analysis (CoA). Purity levels, typically ranging from 95% to 99%, should be confirmed based on intended use. Packaging options vary, with common choices including drums and small containers for laboratory-scale purchases. Buyers should also verify the supplier's compliance with international safety and quality standards, such as ISO or GMP certifications, where applicable.
