Description

(E)-1,2-Dibromo-1,2-Diphenylethene is a high-purity, stereochemically defined brominated alkene building block. This compound matters as a versatile and valuable intermediate for synthesizing complex organic molecules, particularly in pharmaceutical and advanced materials research. It is needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries for constructing functionalized stilbene derivatives and other fine chemicals.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of potential drug candidates, especially those containing a stilbene core or requiring bromine atoms for further functionalization.
• Agrochemical Synthesis: Used in the research and development of novel pesticides and herbicides, where the dibromoethene moiety can act as a precursor for other functional groups.
• Material Science Research: Serves as a monomer or precursor for the development of organic semiconductors, liquid crystals, and photoresponsive polymers.
• Organic Synthesis Reagent: Employed in cross-coupling reactions (e.g., Suzuki, Heck) and as a substrate for elimination or substitution reactions to create diverse alkene and alkyne products.
• Chemical Research Standard: Used as a reference standard or a model compound in analytical chemistry and mechanistic studies.
