Dibutylamine

Dibutylamine (CAS 111-92-2, EC 203-921-8), also known as DNBA, Di-n-butylamine, or N-Dibutylamine, is a secondary aliphatic amine with the molecular formula C8H19N. It carries no assigned E-code. It belongs to the amine chemical category and is supplied as a liquid.

In polymer and rubber processing, dibutylamine acts as a crosslinking agent and curing accelerator by reacting with functional groups to form stable network structures. In food and fragrance applications it functions as a flavorant precursor, while in chemical synthesis it serves as a catalyst and pH buffer, neutralizing acidic intermediates and controlling reaction equilibria.

Dibutylamine is available in standard industrial grades and is subject to REACH registration requirements within the European Union. It is handled under HS code 29211990. Buyers should confirm grade specifications, SDS documentation, and packaging formats directly with the supplier to ensure compliance with their application requirements.
