2,4,6-Tris(dimethylaminomethyl)phenol is a fast tertiary-amine accelerator — the classic accelerator for epoxy cures and a catalyst in polyurethane and other systems. Identity: CAS 90-72-2.
What it is
Tris(dimethylaminomethyl)phenol (CAS 90-72-2) is a liquid tris(aminomethyl)phenol. Its three dimethylaminomethyl groups on a phenol make it a strong, fast accelerator.
How it catalyzes
It strongly accelerates epoxy cure (with anhydride and amine hardeners) and catalyzes urethane and other reactions; the phenolic OH adds to its activity. It gives fast cure, so it is dosed carefully.
Applications
Tris(dimethylaminomethyl)phenol is used as an epoxy cure accelerator (adhesives, coatings, composites) and as a polyurethane/other catalyst. Related amine accelerator: BDMA; see the epoxy curing agents guide.
Forms, grades and handling
This product is supplied as a clear-to-amber liquid in drums, IBCs and bulk. Properties are typical reference values; the Certificate of Analysis (CoA) for the lot you buy governs. Amine catalysts are typically corrosive and have a strong odor — handle per the current Safety Data Sheet (SDS). Each lot ships with CoA, TDS and SDS.
Bulk supply and RFQ
RawSource sources tris(dimethylaminomethyl)phenol direct from producers in bulk, with CoA, TDS and SDS per lot. Tell us your system (flexible/rigid foam, CASE), the reaction balance you need (gel vs blow), and any low-emission requirement, and we will quote the right catalyst or blend. See the full range and gel/blow selection logic in the polyurethane catalysts guide.

Frequently Asked Questions
What is tris(dimethylaminomethyl)phenol used for?
2,4,6-Tris(dimethylaminomethyl)phenol (CAS 90-72-2) is a fast tertiary-amine accelerator for epoxy cures (with anhydride and amine hardeners) and a catalyst in polyurethane and other systems.
How is bulk tris(dimethylaminomethyl)phenol supplied and quoted?
RawSource supplies tris(dimethylaminomethyl)phenol in bulk with CoA, TDS and SDS per lot. Pricing is quote-based on grade and volume; submit an RFQ with your PU system and the gel/blow balance you need.
What is the REACH and TSCA regulatory status of 2,4,6-Tris(dimethylaminomethyl)phenol (CAS 90-72-2)?
2,4,6-Tris(dimethylaminomethyl)phenol (CAS 90-72-2) is subject to U.S. TSCA Inventory requirements; supplying it into the EU requires valid REACH registration ((EC) No 1907/2006). RawSource cannot verify a third-party supplier's registrations — buyers should require documented TSCA and REACH compliance for their jurisdiction and volume (EC 202-013-9).
