Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of cannabinoid receptor modulators. Its alkyne functionality allows for efficient coupling reactions, such as Sonogashira or click chemistry, enabling the construction of complex heterocyclic systems. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its ability to enhance binding affinity and metabolic stability in target molecules. Also utilized in the preparation of analogs for biological evaluation in neuropharmacology research.
