Used in the synthesis of pharmaceuticals, particularly in the production of active ingredients like anticonvulsants and anti-inflammatory agents. It serves as a key intermediate in the preparation of succinate esters, which are employed as plasticizers and in the formulation of biodegradable polymers. Commonly utilized in the agrochemical industry for the development of pesticides and plant growth regulators. Plays a role in the manufacture of dyes and pigments by modifying molecular structure for improved color fastness. Applied in peptide chemistry as a protecting group reagent during amino acid coupling. Also used in surface modification of materials to introduce carboxylic acid functionality for enhanced adhesion or biocompatibility.
