Used in the synthesis of specialty polymers and functional materials, particularly in the development of liquid crystal monomers and crosslinking agents. Its bifunctional structure, featuring both carboxylic acid and ester-linked reactive sites, enables it to act as a spacer or linker in advanced organic frameworks. Commonly employed in the formulation of reactive mesogens for electro-optical devices and high-performance coatings. Also finds use in research settings for modifying surface properties and building block synthesis in supramolecular chemistry.
