Overview
Dibutylamine (CAS 111-92-2 ), commonly abbreviated as DBA, is a secondary aliphatic amine used across polymer processing, agrochemical synthesis, and specialty chemical manufacturing. It functions primarily as a catalyst and curing agent.
This chemical serves as a vital intermediate in reactions requiring a moderately basic, nucleophilic nitrogen source. In rubber and polymer processing, it acts as an accelerator and cross-linking agent, contributing to vulcanization and resin cure systems.
Agrochemical producers use it as a building block for herbicide and fungicide synthesis. Controlled reactivity with acid chlorides and isocyanates is critical for these specific industrial applications and chemical formulations.
In corrosion inhibitor formulations, it provides pH buffering and metal surface protection in industrial fluids. It is also utilized in metalworking compounds to ensure long-term stability and performance of the finished product.
Personal care formulators incorporate this amine as a neutralizing agent and intermediate. It is essential in the production of emulsifiers and conditioning actives used in various consumer and professional cosmetic products.
The product is supplied as a clear to pale yellow liquid in standard drum and IBC quantities. Bulk tanker options are available for high-volume buyers requiring consistent supply for large-scale manufacturing operations.
It is offered in technical grade for industrial synthesis and process applications. Purity specifications typically range from 99% upward, ensuring high performance in sensitive chemical reactions and industrial processes.
Documentation provided with each shipment includes a COA, SDS, and purity confirmation by GC analysis. This ensures compliance with strict industrial safety and quality control protocols for all chemical procurement needs.
