Description

2,3-Diethylsuccinic Acid CAS NO 1186-79-4 is a versatile dicarboxylic acid derivative characterized by its two ethyl side chains on the succinic acid backbone. This structural feature makes it a valuable chiral building block and intermediate in advanced organic synthesis. It is particularly sought after by R&D and production teams in the pharmaceutical, agrochemical, and specialty polymer industries for creating complex molecules with specific stereochemical and physical properties.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of active pharmaceutical ingredients (APIs), especially those requiring specific stereocenters.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and plant growth regulators.
• Polymer & Resin Modifier: Serves as a monomer or cross-linking agent to modify the properties of polyesters, alkyd resins, and other polymers.
• Ligand & Catalyst Preparation: Employed in the synthesis of chiral ligands for asymmetric catalysis and metal-organic frameworks (MOFs).
• Fine Chemical Production: A precursor for flavors, fragrances, and other high-value specialty chemicals.
• Research & Development: Used in academic and industrial labs for methodological studies in organic chemistry and material science.
