Used as a key intermediate in the synthesis of hydrazone-based coordination compounds and metal-organic frameworks (MOFs), this compound plays a significant role in developing sensors and catalysts due to its ability to chelate metal ions. Its extended π-conjugated system makes it suitable for applications in fluorescent probes and optoelectronic materials. Additionally, it serves as a building block in medicinal chemistry for designing bioactive molecules, particularly in studies exploring antimicrobial and anticancer agents. The presence of both carboxylic acid and hydrazone functionalities allows for easy functionalization and integration into larger molecular architectures.
