Coclauril is primarily used as an intermediate in the synthesis of various pharmaceutical compounds, particularly those targeting the central nervous system. It plays a role in the development of certain alkaloid-based medications, which may exhibit analgesic, antiarrhythmic, or neuroactive properties. Due to its structural characteristics, it is valuable in research settings for exploring new bioactive molecules and in the optimization of drug candidates for improved efficacy and selectivity. Its application is mostly confined to laboratory and industrial research rather than direct therapeutic use.
