Description
1-Pentanol (CAS 71-41-0) is a straight-chain primary alcohol also known as amylol, n-amyl alcohol, and n-C5H11OH. It carries EC number 200-752-1 and HS code 29051990. No E-code designation applies to this substance.
In food and flavor applications, 1-pentanol functions as a flavorant by contributing characteristic fruity and fermented notes at controlled concentrations. In polymer processing, it acts as a crosslinker and heat stabilizer, participating in curing reactions that build network structure and retard thermal degradation. Personal care formulators use it as a fragrance carrier and pH buffer in emulsion systems.
1-Pentanol is available in technical and FCC-grade forms, supporting food-contact and industrial applications respectively. The substance is registered under REACH and complies with standard European chemical handling requirements. Typical packaging includes drums and IBC containers, with documentation available upon request.
