Schiff base (named after Hugo Schiff) is a compound with the general structure R1R2C=NR' (R' ≠ H).

They can be considered a sub-class of imines, being either secondary ketimines or secondary aldimines depending on their structure — Schiff, Ugo (1866)

An organic compound formed by a reaction between an aldehyde or ketone with a primary amine, e.g. hydroxycitronellal forms a Schiff s base with methyl anthranilate to give Aurantiol® — David Pybus and Charles Sell 

The Schiff’s bases are less reactive than the free aldehyde and, since the molecular weight is much higher, they are less volatile. Thus, loss of the aldehyde by both chemical reaction and evaporation is slowed down. Moreover, hydrolysis of the Schiff’s base releases both the aldehyde and the methyl anthranilate, both of which have intense odors. Thus, use of a Schiff’s base generates a long-lived fragrance composition of the two ingredients. 

Originally, the aldehydes used in these Schiff’s bases also had sweet, floral odours and so an harmonious accord was produced. Giorgio (Methyl Anthranilate + Helional) is an example of a fragrance which relies heavily on this type of accord.
