Methyl 2-nonynoate(CAS: 111-80-8)

Methyl 2-nonynoate (CAS: 111-80-8) is a liquid with a characteristic odor. It has a molecular weight of approximately 130.23 g/mol and is slightly soluble in water. It is reactive towards bases and can undergo hydrolysis. The compound is flammable and has a flash point of 116°C. It is miscible with many organic solvents.

Methyl 2-nonynoate is typically synthesized via an esterification reaction of 2-methyl-2-hexen-4-yne with methanol in the presence of an acid catalyst, such as sulfuric acid. The reaction conditions include a temperature range of 100-120°C and a yield of up to 85% is often achieved. This process requires careful control of the reaction temperature to avoid side reactions.

Methyl 2-nonynoate is used in various industries, including the fragrance and flavor industry, where it is added to perfumes and food products for its characteristic odor. It is also used in the pharmaceutical industry for the synthesis of certain compounds. Additionally, it can be used in the polymer industry as a plasticizer.

When handling Methyl 2-nonynoate (CAS: 111-80-8), it is essential to wear appropriate personal protective equipment (PPE), including gloves, goggles, and a lab coat. The substance should be handled in a well-ventilated area or a fume hood to avoid inhalation. Spills should be cleaned up immediately using appropriate absorbent materials. Safety data sheets (SDS) should be consulted for detailed handling and emergency procedures. Storage should be in a cool, dry place away from incompatible materials and ignition sources.
