Description
N-Propanol (CAS 71-23-8), also known as 1-propanol and listed under FEMA 2928, is a short-chain aliphatic alcohol with the molecular formula C3H8O. It carries no assigned E-code and is commercially distributed under both propanol and 1-propanol designations across European markets.
In plastics and polymer processing, N-propanol functions as a crosslinker by reacting with isocyanate or resin systems to build molecular network density. In printing and packaging, it acts as a solvent carrier, controlling ink viscosity and evaporation rate during high-speed press runs. Food and fragrance applications exploit its FEMA 2928 status as a flavorant and carrier solvent.
N-Propanol is available in technical, pharmaceutical (Ph.Eur.), and food-grade (FCC) specifications, supporting procurement across regulated industries. It falls under REACH registration requirements within the EU and is classified under HS code 29051200. Standard packaging includes IBC containers and bulk tanker supply for industrial volumes.
