4-Dodecanolide(CAS: 2305-05-7)

4-Dodecanolide (CAS: 2305-05-7) is a colorless or light yellow crystalline compound with a molecular weight of approximately 246.36 g/mol. It has a solubility of about 1.2 g/L in water at 25°C. The compound is relatively stable under normal conditions but undergoes hydrolysis when exposed to acidic or basic conditions. It is soluble in polar solvents like ethanol and acetone, but less soluble in non-polar solvents such as hexane.

4-Dodecanolide (CAS: 2305-05-7) is usually synthesized through the esterification of dodecanol with a suitable acid, such as acetic acid, using a catalyst like sulfuric acid. The reaction is typically carried out under reflux conditions to drive the reaction to completion. The yield is generally around 90%, and the product can be purified by recrystallization from ethanol or acetone.

4-Dodecanolide (CAS: 2305-05-7) is used in various industries. It is a key component in the production of fragrance and flavor compounds due to its pleasant floral and fruity aroma. It also finds applications in the pharmaceutical industry as a solubilizing agent and in the textile industry for improving the dyeability of fibers. Additionally, it is used in the formulation of certain cosmetic products and as a component in certain types of sensors.

When handling 4-Dodecanolide (CAS: 2305-05-7), it is essential to wear appropriate personal protective equipment (PPE), including gloves and safety goggles. It should be handled in a well-ventilated area or in a fume hood to avoid inhalation of the vapor. Spills should be cleaned up immediately using absorbent materials, and the area should be flushed with water. Always refer to the Safety Data Sheet (SDS) for emergency procedures and first aid instructions. Storage should be in a cool, dry place, away from sources of ignition and heat.
