This is a reactive (low-emission) gelling catalyst for polyurethane — a tertiary amine bearing a hydroxyl group that reacts into the polymer matrix, so it does not migrate or fog and gives low VOC/emission foam. Identity: CAS 2212-32-0.
What it is
2-[2-(Dimethylamino)ethyl-methylamino]ethanol (CAS 2212-32-0) is a liquid amino-alcohol catalyst. Its hydroxyl group lets it become chemically bound into the urethane network during cure.
How it catalyzes
It catalyzes the gel (urethane) reaction while reacting into the polymer via its OH group, so it is not released as an emission — the basis of low-emission / low-fogging foam for automotive interiors and similar uses.
Applications
It is used in low-emission flexible and molded polyurethane foam (e.g. automotive interior) and CASE, often replacing fugitive amines. Compare conventional gelling catalyst TEDA.
Forms, grades and handling
Supplied as a clear 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 2-[2- 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 this reactive gelling catalyst used for?
2-[2-(Dimethylamino)ethyl-methylamino]ethanol (CAS 2212-32-0) is a reactive (low-emission) gelling catalyst for polyurethane; its hydroxyl group reacts into the polymer so it does not migrate or fog, used in low-emission automotive and molded foam.
What is a reactive (low-emission) amine catalyst?
A reactive catalyst carries an OH or NH group that chemically bonds into the polyurethane network during cure, so it is not released as a volatile emission — reducing VOC, odor and fogging versus conventional fugitive amine catalysts.
How is bulk this reactive gelling catalyst supplied and quoted?
RawSource supplies this reactive gelling catalyst 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 Trimethylaminoethylethanolamine (Reactive Amine Polyurethane Catalyst)?
Trimethylaminoethylethanolamine (Reactive Amine Polyurethane Catalyst) (CAS 2212-32-0) 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 218-658-4).
