Description

n-Butylamine (CAS 109-73-9 ), also recognized by its FEMA 3130 designation in flavor applications, is a primary aliphatic amine used across chemical synthesis, polymer processing, and flavor manufacturing. It functions as a reactive intermediate and pH modifier in a broad range of industrial formulations. In flavor and fragrance production, n-butylamine contributes to the synthesis of aroma compounds. The material is approved under FEMA 3130 for use in food-grade flavor systems. Polymer and rubber manufacturers use it as a curing agent and cross-linking intermediate in various industrial processes. It is particularly useful in the production of vulcanized rubber and epoxy systems. Personal care formulators incorporate it as a pH-adjusting agent in products where controlled alkalinity is required. This chemical also serves as a building block in the synthesis of agrochemical intermediates, pharmaceuticals, and corrosion inhibitors. n-Butylamine is supplied as a liquid, typically in drums or IBCs. Bulk tanker quantities are suited to industrial-scale procurement for large facilities. Technical grade is the standard commercial offering, with high-purity grades available for flavor and pharmaceutical synthesis. Buyers should confirm concentration and grade specifications against their regulatory requirements. This is particularly important for food-contact or flavor end uses to ensure compliance with safety standards. Contact us for supply of n-Butylamine Request Quote
