TCI B6421 [(Prop-2-yn-1-yloxy)methyl]benzene (CAS 4039-82-1), also known as benzyl propargyl ether, is a versatile non-heterocyclic building block bearing a terminal alkyne. The alkyne group makes it a convenient partner for copper-catalysed azide–alkyne cycloaddition and Sonogashira-type coupling reactions. Its benzyl ether portion serves as a stable yet removable linker element in multi-step synthetic routes. Handle the material in a fume hood, keep it away from ignition sources, and store it tightly sealed in a cool, dark place.
