Obtaining specific aldehyde products from reagents other than toluene tends to be difficult due to rearrangements. Oxidation of toluene to benzaldehyde is quite a useful conversion.

Benzaldehyde can serve as a precursor for various compounds, including dyes, perfumes, and pharmaceuticals. Canadian Journal of Chemistry.
