Overview

Prop-2-en-1-ol (CAS 107-18-6) is an unsaturated primary alcohol with reactive allylic properties and significant industrial applications. This three-carbon allylic alcohol, also known by its IUPAC name prop-2-en-1-ol, represents a crucial intermediate in organic synthesis and industrial chemistry. With the molecular formula C3H6O and a molecular weight of 58.08 g/mol, this compound features both a carbon-carbon double bond and a hydroxyl group, making it highly versatile for chemical transformations. The presence of the allylic structure, where the hydroxyl group is adjacent to a double bond, imparts unique reactivity patterns that distinguish it from saturated alcohols. The compound presents significant safety considerations, classified under multiple hazard categories including flammable liquid (Category 2) and acute toxicity (Category 3). The danger signal word and associated GHS pictograms (GHS02, GHS06, GHS09) reflect its flammable nature and toxicological properties. Its ADR classification as Class 6.1 indicates toxic substances requiring careful handling and transportation protocols. Proper ventilation, appropriate personal protective equipment, and adherence to storage guidelines are essential for safe handling. Industrially, prop-2-en-1-ol serves as a key building block in the synthesis of various chemicals, including polymers and pharmaceutical intermediates. It finds application in the production of specialty chemicals and as a reactive monomer in polymerization processes. The compound is also utilized in organic synthesis reactions where allylic alcohols are required. Related compounds such as prop-2-enal share similar structural features but exhibit different reactivity profiles due to the aldehyde functionality versus the alcohol group. OYSI maintains reliable supply chains for prop-2-en-1-ol, ensuring consistent availability for European industrial customers requiring this specialized chemical intermediate.
