Benzaldehyde s most important use is in organic synthesis, where it is the raw material for a large number of products. In this regard, a considerable amount of benzaldehyde is utilized to produce various aldehydes, such as cinnamic, methyl cinnamic, amyl cinnamic, and hexyl cinnamic. 

Higher still up the series are amyl cinnamic alcohol and aldehyde. These are comparatively large molecules containing 14 carbon atoms, and their odors are therefore relatively similar in type, although there is still a very considerable difference in strength. Here the characteristic aldehydic note is almost missing from the aldehyde, though this may be due partly to the protective influence of the side chain. 

In the first type, which includes aldehyde C12 lauric and phenylacetaldehyde, the balance of the reaction lies in favor of the combined molecule. In the second, however, to which belong aldehyde C12 MNA, cyclamen aldehyde, hydratropic aldehyde, and Lilial, the balance lies more toward the original material. Most ketones also behave in this way. The third type, which includes amyl and hexyl cinnamic aldehydes, do not undergo the aldol reaction and are therefore more stable. Aldehydes such as anisaldehyde and Triplal, in which the —CHO is linked directly to a ring structure, are also less reactive.
