Description

Tripropylamine (CAS 102-69-2 ), also abbreviated as TPA, is a tertiary aliphatic amine used across pharmaceutical synthesis, agrochemical manufacturing, and polymer chemistry. It functions primarily as a catalyst and pH buffer. This chemical serves as a solvent in reactions requiring a non-nucleophilic base with moderate volatility. In pharmaceutical and fine chemical synthesis, it acts as a base catalyst or acid scavenger in condensation reactions. Controlled basicity is critical to yield and purity during acylation processes. Agrochemical formulators use it to neutralize acidic herbicide and pesticide concentrates, improving stability and handling characteristics of the final formulation. In polymer and resin production, it serves as a curing catalyst and process aid. This is particularly useful in systems where a slower-acting tertiary amine is preferred over more reactive alternatives in the manufacturing cycle. Lubricant and metalworking fluid manufacturers incorporate it as a pH stabilizer to extend fluid service life. This application helps reduce corrosion in metal-cutting applications and maintains the integrity of industrial fluids. The product is supplied as a clear liquid in standard drum and IBC quantities, with bulk tanker options available for high-volume industrial buyers. Technical grade is the most common commercial specification for this amine. Purity is typically maintained at 99% or above to meet industrial requirements. It is also listed under FEMA 4247 , which is relevant for flavor and fragrance procurement channels requiring documented ingredient status. Contact us for supply of Tripropylamine Request Quote
