Used as a key intermediate in the synthesis of liquid crystal monomers, particularly in the production of reactive mesogens for advanced display technologies. Its hydroxyl and carboxylic acid functional groups allow for easy modification and incorporation into larger polymer networks, making it valuable in creating cross-linked liquid crystal materials with enhanced stability and electro-optical performance. Also applied in the development of optical films and alignment layers due to its ability to form ordered structures. Additionally, it serves as a building block in specialty polymers and coatings where thermal and chemical resistance are required.
