NO!! A Schiff's Base is the reaction product between an ALdehyde and a compound containing an animo group (NH2); often, in Perfumery this is Methyl Anthranilate. A Schiff's Base is already reacted. When you mix the Aldehyde and Amino Group material, you produce the Schiff's Base and water. When you add an aldehyde plus Methyl Anthranilate to your perfume, you can produce all sorts of reaction products; and water. You don't want that, as it is uncontrolled.
