Description

Ethyl 4-Formylpicolinate CAS NO 189819-76-9 is a high-purity, versatile chemical building block featuring both an aldehyde and an ester functional group on a pyridine core. This unique bifunctional structure makes it a critical intermediate for synthesizing complex molecules in advanced research and development. It is primarily sought after by pharmaceutical, agrochemical, and specialty chemical manufacturers for constructing active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: A key synthon for the development of novel active pharmaceutical ingredients (APIs), particularly in kinase inhibitor and other heterocyclic drug discovery programs.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and insecticides, where the pyridine moiety contributes to biological activity.
• Ligand and Catalyst Development: Serves as a precursor for creating sophisticated chelating ligands and organocatalysts used in asymmetric synthesis and metal complexation.
• Material Science Research: Employed in the synthesis of functional organic materials, such as metal-organic frameworks (MOFs) and organic semiconductors, due to its rigid, coordinating structure.
• Chemical Biology Probes: Utilized as a building block for creating fluorescent tags, affinity probes, and other tools for biochemical research.
• Custom Synthesis and Contract Manufacturing: An essential starting material for custom synthesis houses serving the fine chemical and life science industries.
