Overview
Cyclopentanediol, also referred to as 1,2-cyclopentanediol, is an organic compound featuring a five-membered carbon ring with two hydroxyl groups. This structure grants it reactivity and versatility in chemical synthesis. It is commonly used as an intermediate in pharmaceuticals and polymers. The compound is synthesized through various chemical processes, including catalytic hydrogenation of cyclopentene derivatives. Its stability and solubility in both water and organic solvents make it suitable for diverse industrial applications. Cyclopentanediol is often preferred for its balanced reactivity and ease of handling.
Physical and Chemical Properties
Cyclopentanediol is a white to off-white crystalline solid with a molecular weight of 102.13 g/mol. It has a melting point of approximately 80-85°C, making it stable at room temperature. The compound is soluble in water and most organic solvents, including ethanol, methanol, and acetone. Its cyclic structure and hydroxyl groups contribute to its reactivity, particularly in esterification and etherification reactions. The diol’s stability under normal conditions ensures it can be stored and transported without significant degradation. These properties make it valuable for laboratory and industrial use.
Main Applications
Cyclopentanediol is primarily used as an intermediate in the pharmaceutical industry, where it contributes to the synthesis of active pharmaceutical ingredients (APIs). Its hydroxyl groups enable it to form esters and ethers, which are crucial in drug development. In polymer chemistry, cyclopentanediol serves as a monomer for producing specialty polyesters and polyurethanes. These polymers exhibit unique mechanical and thermal properties, making them suitable for high-performance materials. Additionally, the compound is employed in the manufacture of adhesives, coatings, and other specialty chemicals.
Safety and Storage
Cyclopentanediol should be handled with care to avoid inhalation, ingestion, or skin contact. Personal protective equipment (PPE), such as gloves and goggles, is recommended when working with this chemical. In case of exposure, rinse affected areas with water and seek medical attention if necessary. Storage conditions are critical to maintaining the compound’s integrity. It should be kept in a cool, dry place, away from direct sunlight and moisture. Properly sealed containers are essential to prevent contamination and degradation. Always follow local regulations for chemical storage and disposal.
B2B Procurement Guide
When procuring cyclopentanediol, verify the CAS number (5057-98-7) and purity specifications to ensure product quality. Suppliers typically offer technical and high-purity grades, with prices ranging approximately $50-$200 per kilogram, depending on quantity and purity. Bulk orders may require custom synthesis, so lead times can vary. Establish clear communication with suppliers regarding delivery schedules and packaging options. For international procurement, consider logistics and regulatory compliance, including shipping restrictions and customs requirements.
