UN 2522: 2-Dimethylaminoethyl methacrylate

49 CFR 172.101 Hazardous Materials Table·ERG 2024

DOT Classification and Shipping

UN 2522 is assigned the proper shipping name 2-Dimethylaminoethyl methacrylate in the U.S. DOT Hazardous Materials Table (49 CFR 172.101). It is classified as a Class 6.1 Toxic Substance material, Packing Group II. Required label(s): 6.1.

Packing group indicates the degree of danger within a hazard class: PG I is high danger, PG II medium, PG III low. The proper shipping name, hazard class, UN number, and packing group together form the basic shipping description that must appear on shipping papers and, where required, on the package and placard.

Emergency Response (ERG Guide 153)

Hazards: TOXIC. Combustible. Corrosive. Causes burns. Toxic fumes when heated.

Fire: Small: dry chemical, CO2, water spray. Large: water spray, foam.

Spill: Do not touch. Stop leak if safe. Use water spray to reduce vapor.

Chemical and Physical Properties

2-dimethylaminoethyl methacrylate appears as a clear colorless liquid. Less dense than water and insoluble in water. Vapors heavier than air and corrosive to eyes and mucous membranes. May polymerize exothermically if heated or contaminated. If polymerization takes place inside a closed container, the container may rupture violently. Produces toxic oxides of nitrogen during combustion. Toxic by skin absorption, ingestion and inhalation. Used to make plastics and in textiles.
