2-Propynoxyethanol

2-Propynoxyethanol (CAS 3973-18-0) is a bifunctional building block combining a terminal alkyne and a hydroxyl group within a single molecule. It is used in polymer chemistry to introduce reactive alkyne handles.

This chemical enables precise structural control during synthesis by introducing hydroxyl functionality into macromolecular architectures. In plastics and polymer manufacturing, it serves as a monomer or chain-end modifier.

Terminal alkyne groups are required for click chemistry-based crosslinking or functionalization. Formulators use it to prepare alkyne-terminated polymers and macromonomers that undergo copper-catalyzed reactions.

These azide-alkyne cycloaddition reactions are essential for network formation. It also functions as a polymerization initiator or co-initiator in various ring-opening polymerization systems.

In these systems, the hydroxyl group acts as the initiating species. Specialty coating and adhesive developers incorporate it when building polymer backbones that require post-synthesis surface modification.

This modification is achieved through alkyne-reactive coupling. The product is supplied as a liquid at standard commercial purity levels, typically 95–98%, suited for research-scale and specialty synthesis.

It is available in laboratory quantities through to multi-kilogram lots depending on supplier capability. No established pharmacopoeial or food-grade specifications apply to this technical material.

Procurement is generally against technical-grade certificates of analysis. This ensures the material meets the specific requirements for industrial and laboratory applications in chemical manufacturing.
