Pentosan(CAS: 37319-17-8)

Pentosan (CAS: 37319-17-8) is a water-soluble polymer with a molecular weight ranging from 1000 to 100,000 Da. It crystallizes in the form of fine white crystals. Pentosan is highly reactive with hydroxyl and ketone groups, making it suitable for several chemical reactions. It has a solubility of up to 50 g/L in water at room temperature.

Pentosan can be synthesized through the condensation polymerization of pentoses, such as xylose. Common methods include acid-catalyzed dehydration and base-catalyzed reactions. The yield and selectivity depend on the reaction conditions and catalysts used. Typically, the yield is around 85-95%, with good control over the degree of polymerization.

Pentosan (CAS: 37319-17-8) finds applications in various industries. In pharmaceuticals, it is used as a viscosifier in injectable solutions. In the polymer industry, it serves as a thickener and stabilizer. Pentosan is also used in sensors and semiconductors due to its unique physicochemical properties.

When handling Pentosan (CAS: 37319-17-8), it is essential to use personal protective equipment (PPE) such as gloves and safety glasses. It should be stored in a cool, dry place, away from direct sunlight and heat sources. In case of a spill, use a fume hood and appropriate absorbent materials. Always consult the Safety Data Sheet (SDS) for detailed handling and disposal information.
