Collection: Terminal Alkynes [Conjugation Chemistry/Click Chemistry]

Terminal Alkynes [Conjugation Chemistry/Click Chemistry] — compiles compounds with terminal alkyne groups (C≡CH) that serve as partners in copper-catalyzed azide-alkyne click reactions (CuAAC), including alcohol and amine derivatives, esters, and biotin-alkyne. These terminal alkyne groups provide a stable and selective conjugation point for molecular labeling.

Terminal Alkynes are used by bioorganic chemistry and materials science researchers for biomolecule conjugation, fluorescence labeling, and polymer assembly through click reactions with azide partners. Derivatives such as biotin-alkyne and alkyne-bearing nitroxide radicals are also used in protein tracking studies, functional surfaces, and preparation of probes for cell imaging.

Pay attention to the position of the alkyne group (true terminal, not internal), the additional functional groups accompanying it, and the purity, which affect click reaction efficiency and conjugation yield. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
