Used primarily in Industrial / Manufacturing, and Plasticizers & Polymer applications, 2,2,4-Trimethyl-1,2-Dihydroquinoline is specifically used in antioxidant, and monomer.
2,2,4-Trimethyl-1,2-dihydroquinoline, also called TMDHQ is a monomer that is used as an antioxidant in styrene-butadiene and nitrile butadiene rubbers and latexes (NTP 1997). It is described by some sources as a dark yellow liquid and by others as a tan powder. It has low volatility and water solubility, and is non-flammable (CAMEO Chemicals Undated, HSDB 2003).
