Vanillin is commonly found as white or off-white needle-like crystals, or as a fine pale-yellow to white powder. It emits a sweet, creamy aroma reminiscent of natural vanilla. The compound is prone to degradation when exposed to moisture, air, or light, gradually oxidizing under humid conditions and being sensitive to sunlight.

It is commonly used in the production of incense powders and bean-like aromatic spices and often serves as a key ingredient in fragrance formulations. Vanillin is widely incorporated into a variety of scents, particularly in blends such as violet, cymbidium, sunflower, and oriental fragrances. When combined with compounds like piperonal, isoeugenol benzyl ether, coumarin, and musk, it functions as a fixative, modifier, and blending agent, while also helping to mask undesirable odors.
