Q: What is 1-Octadecanol (CAS: 112-92-5)?

1-Octadecanol is a long-chain primary alcohol with the chemical formula C18H38O. It is a waxy, colorless liquid with a high molecular weight and is commonly used as a raw material in the production of surfactants, lubricants, and other specialty chemicals. It has a melting point of around 25–30°C and is soluble in organic solvents but not in water.

Q: What are the main uses of 1-Octadecanol (CAS: 112-92-5)?

1-Octadecanol is primarily used in the manufacture of surfactants, lubricants, and emulsifiers. It also serves as a component in the production of certain pharmaceuticals, such as antifungal agents, and finds applications in the cosmetic and food industries as a stabilizer. In research, it is used as a solvent and in the synthesis of more complex organic compounds.

Q: Is 1-Octadecanol (CAS: 112-92-5) safe?

1-Octadecanol is generally considered safe when handled properly. It has low toxicity and is not classified as a hazardous substance under many regulatory frameworks. However, it should be handled with care to avoid skin contact and inhalation. Safety data sheets (SDS) recommend using appropriate personal protective equipment (PPE) and ensuring good ventilation during handling.

Q: How should 1-Octadecanol (CAS: 112-92-5) be stored?

1-Octadecanol should be stored in a cool, dry place away from direct sunlight and sources of heat. It is stable under normal storage conditions but should be kept in tightly sealed containers to prevent evaporation and contamination. Avoid exposure to air and moisture to maintain its quality and effectiveness.
