4-propylbenzaldehyde

4-Propylbenzaldehyde (CAS 28785-06-0 ) is an aromatic aldehyde used as a building block in pharmaceutical synthesis and fragrance formulation. Its para-substituted benzaldehyde structure makes it a recognized intermediate for constructing more complex active compounds.

In pharmaceutical manufacturing, it serves as a key synthetic intermediate for preparing APIs and specialty compounds where a propyl-substituted aromatic aldehyde scaffold is required. This material is essential for high-precision chemical engineering.

Fragrance chemists incorporate it into fine fragrance and functional fragrance formulations to contribute aldehydic, floral-green character to finished compositions. It provides a unique olfactory profile for premium consumer products.

It also supports the synthesis of liquid crystal compounds, where para-alkyl benzaldehyde derivatives are established structural components. These applications are critical for the development of modern display technologies and electronics.

Specialty chemical producers use it as a precursor in condensation and reductive amination reactions targeting novel molecular architectures. Its reactivity makes it a versatile tool for research and development laboratories.

4-Propylbenzaldehyde is supplied as a liquid, typically offered at high purity levels suited for pharmaceutical intermediate and research-grade applications. The material maintains stability under standard industrial storage conditions.

Standard packaging ranges from small laboratory quantities through to bulk drum supply, depending on the supplier's production scale. Technical-grade material is the most commonly traded specification in the global chemical market.
