Description
N,N-Dimethyl-p-toluidine (CAS 99-97-8, EC 202-805-4) is a tertiary aromatic amine supplied as a light yellow liquid, also referenced under the names 4-dimethylaminotoluene, N,N,4-trimethylaniline, and dimethyl-p-tolyl-amine. It carries no assigned E-code and is catalogued under HS code 29214300.
In polymer and coatings applications, it functions as a room-temperature accelerator for peroxide-initiated curing systems, activating benzoyl peroxide to generate free radicals without applied heat. It also serves as a co-initiator in UV-curable printing inks, where it donates electrons to excited photoinitiators to accelerate crosslinking, and appears as a flavoring agent in food and nutrition formulations.
This material is available in standard industrial grades and is subject to REACH registration requirements within the EU. Procurement teams should confirm current SDS documentation and substance restrictions before ordering. Packaging formats and minimum order quantities are available on request from our sales team.
