In 1921, the first use of synthetic aldehydes in perfumery was introduced, notably in Chanel No. 5, which featured a clean and abstract scent profile. This innovation marked a turning point in the fragrance industry, allowing for the creation of complex scents that were previously unattainable with natural ingredients alone. The use of aldehydes not only transformed the art of perfumery but also influenced cultural perceptions of fragrance and luxury.

The first use of aldehydes in perfumery in 1921 symbolized a modernist break with tradition, inspiring avant-garde poets to experiment with new sensory languages. This innovation influenced poetry that sought to capture the ephemeral nature of experience and perception.
