What is Pentylamine?

Pentylamine (CAS 110-58-7), also known as amylamine and recognized under FEMA 4242, is a primary aliphatic amine used in chemical synthesis and industrial processing.

Where is Pentylamine used?

  • Agrochemical manufacturing: intermediate in the synthesis of herbicides and fungicides
  • Pharmaceutical production: building block for API synthesis, where its primary amine group enables condensation and alkylation reactions with drug precursors
  • Metalworking and industrial water treatment: corrosion inhibitor, forming protective films on metal surfaces in fluid formulations
  • Polymer chemistry: chain initiator or modifier in polymerization processes, influencing molecular weight and end-group functionality in specialty resins
  • It functions as a reactive building block, pH modifier, and corrosion inhibitor depending on the application context.

Good to know: Buyers sourcing for pharmaceutical intermediates should confirm purity levels and documentation requirements with their supplier prior to procurement. Proper handling and storage are required to maintain product stability.

Commercial specifications

  • Standard packaging ranging from drums to ISO tank containers for bulk orders
