Uses
Uses in perfumery :
Caproic Acid is used in very small quantity in cheese and lavender notes.
Year of discovery :
Data not available.
Natural availability :
Caproic Acid can be obtained naturally, as it is present in many plant extracts, such as Lavender EO, Petitgrain EO or Lemongrass EO. Therefore, it can be extracted from these essential oils by fractional distillation.
Isomerism :
Ethyl Butyrate is a constitutional isomer of Caproic Acid. Indeed, Ethyl Butyrate has a very butyric and cheesy note.
Synthesis precursor :
Caproic acid is the precursor for the synthesis of several esters called ''caproates '', by reacting it with an alcohol, in the presence of an acid catalyst.
Synthesis route :
Caproic acid is synthesized from chloropentane by a two-step reaction, by reaction with sodium cyanide, followed by hydrolysis.
