Used as a key intermediate in the synthesis of meloxicam derivatives for pharmaceutical research, particularly in developing targeted drug delivery systems. Its carboxy functional group allows conjugation with carriers like polymers or antibodies, enabling site-specific anti-inflammatory or anticancer therapies. Also employed in immunoassay development as a hapten to generate antibodies for detecting meloxicam in biological samples. Widely applied in preclinical studies to evaluate metabolic pathways and improve drug efficacy with reduced side effects.
