Description

Epoxypropionic Acid CAS NO 503-11-7 is a versatile bifunctional organic compound featuring both an epoxide ring and a carboxylic acid group. This unique structure makes it a valuable intermediate for synthesizing a wide range of specialty chemicals and polymers. It is essential for manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors seeking to introduce reactive functionality into their products.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring chiral centers or specific reactive handles for conjugation.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators, where its epoxide group enables ring-opening reactions to create complex molecular architectures.
• Polymer & Resin Modifier: Serves as a cross-linking agent or a reactive diluent in epoxy resin systems, and as a monomer for producing specialty polyesters and coatings with enhanced adhesion and chemical resistance.
• Fine Chemical Production: Intermediate for manufacturing dyes, pigments, and complex organic compounds in research and industrial-scale fine chemical synthesis.
• Bioconjugation & Linker Chemistry: Utilized in biochemical research and diagnostic reagent development for creating covalent linkages between molecules via its carboxylic acid and epoxide functionalities.
