Safety classification and hazard statements

Physical description and handling notes

• Dimethylethylamine, [liquid] appears as a clear colorless liquid with a strong odor that can vary from ammonia-like to fishlike. Vapors irritate the eyes and mucous membranes. Less dense than water. Vapors heavier than air. Produces toxic oxides of nitrogen during combustion. Used in the manufacture of other chemicals.
• Liquid
• Clear colorless liquid with a strong odor of ammonia or fish; [CAMEO]
• Odor threshold measurements on 16 aliphatic amines were made with panels of specific anosmic & normal observers. The anosmia was most pronounced with low-mol-wt tertiary amines, but was also observed with lesser degree with primary & secondary amines.
• Index of refraction: 1.3705 at 25 °C/D
• pKa = 10.16 (conjugate acid)
