Description

Cycloheptanone Oxime CAS NO 2158-31-8 is a versatile seven-membered cyclic ketoxime, a key organic intermediate in fine chemical synthesis. Its value lies in its reactive oxime functional group, which serves as a crucial precursor for the production of caprolactam analogs, specialty polymers, and various nitrogen-containing compounds. This product is essential for R&D laboratories and manufacturers in the pharmaceutical, agrochemical, and polymer industries seeking to develop novel molecules and materials.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of novel therapeutic agents, particularly those containing seven-membered nitrogen heterocycles.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and plant growth regulators that require specific cyclic oxime structures.
• Polymer & Resin Modifier: Acts as a cross-linking agent or monomer in the development of specialty polyamides and high-performance resins.
• Organic Synthesis Reagent: A valuable reagent for Beckmann rearrangement reactions to produce corresponding lactams, and for the formation of nitrones and other N-O functional groups.
• Chemical Research & Development: Employed in academic and industrial R&D for exploring new reaction pathways and creating complex molecular architectures.
• Corrosion Inhibitor Formulation: Used as a component in specialized formulations designed to protect metals in industrial settings.
