3-(2-Iodoethoxy)prop-1-yne is an iodo-substituted propargyl ether used as an alkyne reagent and electrophile in organic synthesis. It is employed in copper-catalyzed azide-alkyne cycloaddition (click chemistry) to introduce propargyl groups and as a handle for nucleophilic substitution, with iodine acting as a good leaving group to enable further functionalization.
- Iodo-substituted propargyl ether suitable for click chemistry.
- Acts as an electrophile; iodine is a good leaving group for substitution reactions.
- Enables introduction of alkyne functionality for bioconjugation and labeling.
- Useful in small-molecule synthesis and crosslinking applications.
- Available in laboratory-scale quantities for synthetic use.

Sigma Aldrich Fine Chemicals Biosciences N tert Butyldimethylsilyl
N-tert-Butyldimethylsilyl-N-methyltrifluoroacetamide is a silylating reagent which replaces the active hydrogen with tert-Butyldimethylsilyl group. The tert-Butyldimethylsilyl derivatives are found to be more resistant to hydrolysis and stable compared to trimethylsilyl (TMS) derivatives. This reagent is suitable for GC-MS analysis since it produces mass spectra which can be easily interpreted. It is widely used for the silylation of different alcohols thiols phenols carboxylic acids amines and amides.
