Ethyloctynol

Ethyloctynol (CAS 5877-42-9) is a propargylic alcohol used as a solvent and carrier in pharmaceutical manufacturing.

Where is Ethyloctynol used?

• Pharmaceutical intermediate synthesis: starting material or reactive solvent in construction of complex ingredients
• Multi-step API synthesis: propargylic alcohol structure supports coupling and reduction reactions
• Drug delivery systems: carrier solvent where conventional glycols are incompatible
• Contract manufacturers working on small-molecule drug candidates use it for exploratory synthesis campaigns.

Good to know: It combines an acetylenic group with a secondary hydroxyl, making it a selective functional building block; this structure is useful where structural diversity in the alcohol component is critical.

Commercial specifications

• Laboratory-scale to bulk industrial quantities
• Purity specifications confirmed by GC analysis
• Glass bottles for small quantities, drums for larger volumes
