Allyl Alcohol

Allyl Alcohol

CAS Number:107‑18‑6

Synonyms:Allyl alcohol; 2‑Propen‑1‑ol; Prop‑2‑en‑1‑ol; Vinylcarbinol; Allylic alcohol

Chemical Formula:C₃H₆O

Product Introduction

Allyl alcohol is a colorless, volatile liquid with a pungent, mustard-like odor. It’s more toxic than typical small alcohols and is used industrially to produce glycidol, allyl ethers, plasticizers, and as a precursor to flame-resistant and specialty materials.
