Natural availability :
Aldehyde C-7 can be found in its natural state, especially in Champaca Absolute, Narcissus Absolute or Damask Rose Absolute (and other roses), from which it can be extracted by fractional distillation.
Year of discovery :
Data not available.
Other comments :
In comparision to other aliphatic aldehydes as Aldehyde C-8, Aldehyde C-7 does not have an aldehydic facet and is much more floral.

Synthesis route :
Aldehyde C-7 is an aliphatic aldehyde. Like the other aldehydes, it can be synthesized by reaction of heptyl halides (chloride, for example) and dimethyl sulfoxide (DMSO), followed by an alklaine treatment with sodium bicarbonate. Other synthetic routes exist such as a reduction of Rosenmund from heptylic acid, using an acid chloride.
Synthesis precursor :
Aldehyde C-7 enters the first stage of synthesis of Neofolione®, in combination with malonic acid. It forms a Schiff base by reaction with Methyl Anthranilate or Indole for example. It can also be used for condensation with another aldehyde or ketone to form the desired alcene.
Isomerism :
Isoamyl acetate and Methyl Amyl Ketone are constitutional isomers of Aldehyde C-7, but have a very different smell: more fruity for Isoamyl acetate and more mushroom for Methyl Amyl Ketone.
