1-Butynylbenzene-d5 is a deuterium-labeled terminal alkyne reagent used as a stable-isotope tracer and click chemistry building block. The d5 labeling provides a characteristic mass shift for mass spectrometry and metabolic studies, while the alkyne enables copper-catalyzed azide-alkyne cycloaddition (CuAAC) for conjugation and synthesis. Supplied in small quantities for analytical and synthetic applications; store and handle under recommended low-temperature conditions.

• Deuterium-labeled (d5) for clear mass-shift detection in mass spectrometry.
• Terminal alkyne functional group suitable for CuAAC click reactions.
• Useful for tracer studies, metabolic profiling, and isotope-labeled synthesis.
• Supplied in small quantities appropriate for analytical or synthetic workflows.
• Long-term stability when stored at -20°C in pure form; follow solvent storage guidelines.
