• Molecular formula C7H11Br and molecular weight 175.07 for synthesis calculations.
• High reported purity: 99.7% (GC), suitable for synthetic workflows.
• Suited for use in PROTAC linker assembly and general medicinal chemistry applications.
• Store under recommended conditions to maintain stability.

Medchemexpress LLC 8-bromooct-1-yne | 81216-13-9 | MFCD20621358 | 189.09 g·mol⁻¹ | C8H13Br | 1 G

8-Bromooct-1-yne is a brominated terminal alkyne reagent used as a synthetic building block in organic synthesis and chemical biology research. It combines a terminal alkyne for click-type reactions with a bromide leaving group for nucleophilic substitution, enabling installation of alkynyl linkers and chain elaboration in probe and linker synthesis.

• Terminal alkyne enables copper-catalyzed azide-alkyne cycloaddition (click chemistry).
• Bromide functions as a good leaving group for nucleophilic substitution and chain modification.
• Suitable as a building block for probes, tags, and linker or PROTAC synthesis.
• Available in small laboratory quantities for research use.
• Handle under inert atmosphere and store cold according to handling guidelines.
