Medchemexpress LLC 1-butynylbenzene-d5 | 1219803-38-9 | 135.22 | C10H5D5 | 25 MG
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.
