(2E)-2-Nonenal(CAS: 18829-56-6)

(2E)-2-Nonenal is a colorless to light yellow liquid with a fruity odor. It has a molecular weight of 130.23 g/mol and a boiling point of 180.2°C. It is slightly soluble in water but miscible with most organic solvents. It is known for its reactivity with amines and nucleophiles, making it useful in organic synthesis.

(2E)-2-Nonenal is commonly synthesized by the hydroformylation of nonene using a rhodium complex as a catalyst. The reaction is carried out under pressure with carbon monoxide and hydrogen, and the product is isolated by distillation. The yield is typically around 70-80%, and the selectivity for the E-isomer is high.

(2E)-2-Nonenal is widely used in the fragrance and flavor industry, as it imparts a fruity aroma. It is also utilized in the production of cosmetic products, as a fixative in perfumes. Additionally, it is used as a precursor in the synthesis of other compounds for pharmaceuticals and as a monomer in the synthesis of certain polymers.

When handling (2E)-2-Nonenal, ensure that appropriate personal protective equipment (PPE) is worn, including gloves, goggles, and a lab coat. Work in a well-ventilated area or a fume hood to minimize inhalation risks. Spills should be cleaned up using appropriate absorbents, and the area should be thoroughly ventilated. Always refer to the Safety Data Sheet (SDS) for detailed handling instructions and safety information.
