(9Z)-(~13~C_18_)-9-Octadecenoic acid(CAS: 287100-82-7)

(9Z)-(~13~C_18_)-9-Octadecenoic acid is a fatty acid with a molecular weight of approximately 282.4 g/mol. It is typically a white to light yellow solid in its crystalline form. The acid has low water solubility and is moderately soluble in organic solvents like ethanol and acetone. It is less reactive than saturated fatty acids but can undergo hydrogenation and other chemical transformations under appropriate conditions.

(9Z)-(~13~C_18_)-9-Octadecenoic acid can be synthesized through the reduction of 9-octadecenal using hydrogen and a catalyst like palladium on carbon. Another method involves the direct reduction of oleic acid. The synthesis typically yields a high selectivity towards the 9-position, with a yield of around 85-90%, depending on the reaction conditions.

(9Z)-(~13~C_18_)-9-Octadecenoic acid is utilized in the pharmaceutical industry for the production of certain drugs and cosmetics. It is also incorporated into polymer formulations for enhancing flexibility and durability. Additionally, the compound finds applications in the development of sensors and semiconductors due to its unique chemical properties.

When handling (9Z)-(~13~C_18_)-9-Octadecenoic acid, it is essential to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area, preferably within a fume hood. Spills should be cleaned up immediately using appropriate absorbents, and the area should be flushed with water. Always consult the Safety Data Sheet (SDS) for detailed handling and disposal information.
