Description

Diphosphonic Acid, Methyl(3-Methyloxiranyl)-, cis-(+)- (9Ci) is a specialized organophosphorus compound characterized by its unique cis-(+)- stereochemistry and the presence of both phosphonic acid and oxirane (epoxide) functional groups. This molecular architecture makes it a valuable high-purity intermediate and ligand precursor for advanced chemical synthesis. It is primarily sought by pharmaceutical researchers and specialty chemical manufacturers developing novel bioactive molecules, metal chelators, and functional materials.

Application

• Pharmaceutical Intermediate: Key chiral building block for the synthesis of novel bisphosphonate drugs targeting bone metabolism disorders.
• Ligand Synthesis: Precursor for creating sophisticated chelating agents and catalysts used in asymmetric synthesis and metal ion sequestration.
• Material Science: Functional monomer for modifying polymer surfaces or creating metal-organic frameworks (MOFs) with specific adsorption properties.
• Agrochemical Research: Intermediate in developing new generation plant growth regulators or herbicides with targeted action.
• Scale Inhibitor Research: Investigational compound for novel water treatment formulations to control scale in industrial systems.
