Product Description:

1,9-Nonanediol is a linear aliphatic diol with the molecular formula C9H20O2, featuring two terminal hydroxyl groups separated by a nine-carbon chain. It is a colorless to pale yellow solid or liquid at room temperature, with a melting point around 45-47буC. This compound serves as a versatile building block in organic synthesis, particularly for the preparation of polyesters, polyurethanes, and polyamides. In polymer chemistry, it acts as a monomer for producing high-performance polymers with enhanced flexibility and hydrophobicity due to its long methylene chain. It is also used as an intermediate in the synthesis of plasticizers, lubricants, and specialty chemicals. Additionally, 1,9-nonanediol finds applications in the production of pharmaceutical intermediates and cosmetic ingredients, where its diol functionality enables crosslinking or chain extension reactions. Its low toxicity and biodegradability make it suitable for green chemistry applications.
