Description

(+/-) Chlorosuccinic Acid CAS NO 617-41-4 is a versatile chiral organic acid derivative, serving as a critical building block in advanced chemical synthesis. Its value lies in its bifunctional structure, featuring both a carboxylic acid and a reactive chloromethyl group, enabling its use in a wide range of coupling and derivatization reactions. This compound is essential for research laboratories and industrial manufacturers in the pharmaceutical, agrochemical, and specialty chemical sectors who require high-purity intermediates for producing active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key starting material or chiral synthon in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring a succinate backbone.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators where the chlorosuccinate moiety is incorporated.
• Polymer Chemistry: Acts as a monomer or cross-linking agent for modifying polymer properties, such as in the creation of functionalized polyesters or hydrogels.
• Organic Synthesis Reagent: Employed in nucleophilic substitution reactions, esterifications, and amide bond formations to introduce carboxylic acid functionality.
• Bioconjugation & Protein Modification: Useful in biochemical research for labeling or modifying biomolecules due to its reactive chloro group.
• Ligand & Catalyst Preparation: Serves as a precursor for synthesizing chiral ligands used in asymmetric catalysis.
