Description

2-Hydroxy-Pent-4-Enoic Acid is a versatile, unsaturated hydroxy acid with a reactive terminal alkene group. This unique bifunctional structure makes it a valuable building block for synthesizing complex molecules in fine chemical and pharmaceutical research. It is particularly sought after by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty polymer industries for creating novel compounds and intermediates.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs) and chiral compounds.
• Agrochemical Synthesis: Building block for developing novel herbicides, fungicides, and plant growth regulators.
• Polymer Modification: Used to introduce hydroxyl and carboxylic acid functionality into polymers, enhancing properties like adhesion and biocompatibility.
• Fine Chemical Production: Serves as a starting material for flavors, fragrances, and other high-value specialty chemicals.
• Cross-linking Agent: The alkene and acid groups allow it to act as a cross-linker in resin and coating formulations.
• Academic & Industrial Research: Valuable reagent for methodological development in organic synthesis and catalysis studies.
