Overview
Ethylbutylamine ( CAS 13360-63-9 ) is a secondary aliphatic amine used across pharmaceutical synthesis, agrochemical production, and polymer chemistry. N-Butylethylamine is a recognized alternative name buyers may encounter in supplier catalogs.
It functions primarily as a chemical intermediate, solvent, and reaction modifier in multi-step industrial processes. In pharmaceutical manufacturing, it serves as a building block for active ingredient synthesis.
It also acts as a buffering agent to control pH in reaction sequences. Agrochemical formulators use it as an intermediate in the production of herbicides and pesticides, where controlled basicity is required.
In polymer and plastics production, it acts as a polymerization initiator or catalyst modifier. This influences chain initiation and molecular weight distribution during the manufacturing of various materials.
Lubricant and metalworking fluid formulators incorporate it as a functional additive. Amine-based pH control improves formulation stability and performance in demanding industrial environments.
Ethylbutylamine is supplied as a liquid in standard drum and IBC packaging suited for industrial volumes. Technical grade is the primary commercial specification for most industrial applications.
Purity levels suitable for pharmaceutical intermediate use are available from select suppliers. Buyers should confirm purity specifications and moisture content when sourcing for GMP-regulated applications.
