clear slightly yellow liquid

Nonanoyl chloride is used for the acylation of amine groups of chitosan to simultaneously improve its material properties and adsorption capacity. It was also used in the synthesis of N-nonanoyl piperonylamide, caged vanilloid, N-(4-hydroxy-3-methoxybenzyl)-N-(2-nitrobenzyl)-nonanoylamide or N-(2-Nitrobenzyl)-N-vanillyl-nonanoylamide, n-benzylnonanamide.

Reflux it with acetyl chloride (~ 3 volumes) for 1hour, then distil off AcCl followed by the nonanoyl chloride at ~12mm. It is moisture sensitive and should be stored in sealed ampoules. [Beilstein 2 IV 1023.]
