Overview
Pentylamine (CAS 110-58-7 ), also known as amylamine and recognized under FEMA 4242 , is a primary aliphatic amine used across chemical synthesis and industrial processing.
It functions as a reactive building block, pH modifier, and corrosion inhibitor depending on the application context. In agrochemical manufacturing, it serves as an intermediate in the synthesis of herbicides and fungicides.
Pharmaceutical producers use it as a building block for API synthesis, where its primary amine group enables condensation and alkylation reactions with drug precursors. This versatility makes it essential for modern medicine.
In metalworking and industrial water treatment, it acts as a corrosion inhibitor, forming protective films on metal surfaces in fluid formulations. This helps maintain the integrity of industrial equipment over time.
Polymer chemists incorporate it as a chain initiator or modifier in polymerization processes, influencing molecular weight and end-group functionality in specialty resins. It is a critical component for material science.
Pentylamine is supplied as a clear liquid in standard packaging ranging from drums to ISO tank containers for bulk orders. Technical and reagent grades are the most common commercial specifications available.
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.
