Description

1,3-Benzenedicarboxaldehyde, Monooxime (9Ci) is a specialized aromatic dialdehyde derivative where one aldehyde group is protected as an oxime. This compound matters as a versatile and reactive synthetic intermediate, offering chemoselectivity for the modification of one aldehyde group while leaving the other available for further transformations. It is primarily needed by researchers and manufacturers in the pharmaceutical and agrochemical industries for the development of active ingredients, as well as in academic and industrial R&D for synthesizing complex organic molecules, ligands, and functional materials.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates, particularly in heterocyclic chemistry.
• Agrochemical Synthesis: Used in the research and development of advanced pesticides and herbicides.
• Ligand and Chelator Preparation: Serves as a precursor for creating Schiff base ligands used in catalysis and metal complexation.
• Polymer and Material Science: Employed in the synthesis of functional monomers and cross-linking agents for specialty polymers.
• Organic Synthesis Research: A valuable tool for chemists exploring selective protection/deprotection strategies and multi-step synthesis routes.
• Chemical Derivatization: Used in analytical chemistry to modify and detect specific functional groups in complex mixtures.
