(3-Chloro-4-fluorophenyl)thiourea is primarily used in research and development within the field of medicinal chemistry. It serves as a key intermediate in the synthesis of various biologically active compounds, particularly those targeting enzyme inhibition. Its structure is often exploited in the design of potential therapeutic agents, especially in the development of inhibitors for specific enzymes involved in disease pathways. Additionally, it finds application in the study of structure-activity relationships (SAR) to optimize drug candidates for improved efficacy and selectivity. Its utility extends to the preparation of derivatives that are screened for antimicrobial, anticancer, or anti-inflammatory properties.
