Description

4-Cyanonaphthalene-1-Carboxaldehyde (CAS NO 62855-39-4) is a versatile naphthalene-based aromatic aldehyde building block. This compound is valued for its bifunctional reactivity, featuring both a formyl group and a nitrile group, which makes it a critical intermediate in advanced organic synthesis. It is primarily sought after by research institutions and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds with naphthalene scaffolds.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and plant growth regulators.
• Ligand and Catalyst Development: Employed in the preparation of specialized ligands for metal-catalyzed cross-coupling reactions.
• Functional Material Precursor: A building block for organic light-emitting diodes (OLEDs), dyes, and pigments due to its conjugated structure.
• Academic and R&D: Utilized in research laboratories for method development and exploring new synthetic pathways in heterocyclic and medicinal chemistry.
• Fine Chemical Production: Integral to the manufacture of complex, high-value specialty chemicals and advanced intermediates.
