FAQ

What is Octanoic acid (CAS: 124-07-2)?

Octanoic acid, also known as caprylic acid, is a saturated fatty acid with the chemical formula C8H16O2. It is a colorless, waxy liquid with a faint, soapy odor. Octanoic acid is soluble in alcohol and ether but has low solubility in water. It is commonly used in various industries due to its unique chemical properties and versatility.

What are the main uses of Octanoic acid (CAS: 124-07-2)?

Octanoic acid is widely used in pharmaceuticals as a precursor for drug synthesis, in the food industry as a flavoring agent, and in cosmetics for its emollient properties. It also finds applications in the production of biodegradable plastics, coatings, and as a solvent. In research, it serves as a building block for organic compounds and is used in analytical chemistry for standards and calibration.

Is Octanoic acid (CAS: 124-07-2) safe?

Octanoic acid is generally considered safe when handled properly, but it can cause skin and eye irritation. It is classified as a mild irritant under safety standards. Protective measures such as gloves, goggles, and proper ventilation should be used when working with it. Always follow OSHA and EPA guidelines for safe handling and disposal.

How should Octanoic acid (CAS: 124-07-2) be stored?

Octanoic acid should be stored in a cool, dry, and well-ventilated area, away from direct sunlight. It is best kept in a sealed container at temperatures below 25°C to maintain stability. Avoid exposure to moisture and ensure proper labeling to prevent accidental contact. Store in a chemical storage cabinet if handling in large quantities.
