(9Z)-9-Hexadecenal(CAS: 56219-04-6)

(9Z)-9-Hexadecenal is a colorless liquid with a strong, grassy odor. Its molecular weight is approximately 254.41 g/mol. It is slightly soluble in water but miscible with organic solvents. Chemically, it is relatively stable but can react with strong oxidizing agents. It is used in flavor and fragrance industries due to its characteristic scent.

(9Z)-9-Hexadecenal is synthesized by the reduction of 9-hexadecenaldehyde with hydrogen in the presence of a catalyst, such as palladium on carbon. The reaction conditions include a pressure of 10-20 atmospheres of hydrogen and a temperature range of 30-50°C. The yield is generally high, around 90%, and the process is selective, producing the desired cis-isomer with high purity.

(9Z)-9-Hexadecenal is widely used in the flavor and fragrance industry due to its distinctive grassy odor. It is also utilized in the food additive sector as a flavor enhancer. Additionally, it has applications in the textile industry as a fragrance base and in the cosmetic industry as a scent ingredient.

When handling (9Z)-9-Hexadecenal, it is important to use appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. It should be stored in a cool, dry place away from heat sources and oxidizing agents. In case of spill, the area should be ventilated, and the spill should be cleaned up using absorbent material. Always refer to the Safety Data Sheet (SDS) for detailed handling and storage instructions.
