1,9-Nonanediol is an important aliphatic diol fine chemical intermediate. It is mainly used to synthesize polyester, polyurethane and polyether polymers, improving material flexibility and low temperature resistance. It serves as raw material for manufacturing high-grade plasticizers, lubricants and surfactants, widely applied in plastic processing and daily chemical industry. It is also adopted to prepare pharmaceutical and pesticide intermediates through esterification and condensation reactions. In spice industry, it can be used to synthesize long-chain ester fragrances. Besides, it acts as organic solvent and chemical reagent for laboratory synthetic research, possessing broad application prospect in polymer material, medicine and fine chemical fields.

This compound owns low toxicity and mild irritation. Inhalation of dust may cause slight respiratory discomfort, keep ventilation and wear dust mask during operation. Skin contact may lead to dry and itchy skin, wash exposed skin with clean water timely. Eye contact will trigger stinging irritation, flush eyes with running water for over fifteen minutes. Accidental intake may cause mild gastrointestinal discomfort. High temperature may trigger decomposition and generate harmful fumes. Store separately from oxidants and edible products. Discarded materials should be handled as common organic waste to prevent unnecessary harm and environmental pollution.
