Description

Dipropylamine (CAS 142-84-7) is a secondary aliphatic amine used as a chemical intermediate and functional additive across pharmaceutical, agrochemical, and industrial manufacturing. It acts as a pH regulator, corrosion inhibitor, and reactive building block in synthesis processes. In agrochemical production, this compound serves as a key intermediate in the synthesis of herbicide salts and active ingredient formulations, particularly for glyphosate-based products. Pharmaceutical manufacturers use it as a synthetic intermediate for drug compounds.

It also serves as a buffering agent in active pharmaceutical ingredient (API) processing. In metalworking and lubricant formulations, it functions as a corrosion inhibitor additive, protecting metal surfaces in cutting fluids and industrial lubricants. Polymer and plastics processing also draws on its amine reactivity for catalyst systems and curing agent preparation. This versatility makes it an essential component in modern chemical manufacturing and material science applications.

The product is supplied as a clear liquid in standard bulk packaging including drums and IBC containers, with isotank options available for larger volumes. It is commercially available in technical grade, suited to industrial synthesis. Pharmaceutical-grade supply exists for API-related applications where tighter purity specifications and documentation requirements apply. We ensure all shipments meet rigorous safety and quality standards for global distribution and handling.
