Description

Butanedioic Acid, (Bromomethyl)-, Diethyl Ester (9Ci) CAS NO 121223-90-3 is a specialized brominated succinate derivative, serving as a versatile chemical building block for advanced organic synthesis. Its molecular structure, featuring both an ester and a reactive bromomethyl group, makes it a critical intermediate for constructing complex molecules. This compound is essential for research and development chemists in the pharmaceutical, agrochemical, and specialty chemical industries seeking to introduce functionalized succinate moieties.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for molecules requiring functionalized succinic acid frameworks.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and plant growth regulators where the bromomethyl group enables further derivatization.
• Ligand and Catalyst Development: Serves as a starting material for creating complex chelating ligands and organocatalysts used in asymmetric synthesis.
• Polymer Modification: Employed to introduce reactive sites or functional groups into polymer backbones for specialty materials with tailored properties.
• Cross-coupling Reactions: The bromomethyl moiety acts as an electrophile in various palladium-catalyzed cross-coupling reactions (e.g., Suzuki, Heck) to form carbon-carbon bonds.
• Academic and Industrial R&D: A valuable reagent for methodological studies and the exploration of new synthetic pathways in organic chemistry.
