Description

Colorless gas at room temperature; fishy ammoniacal odor; readily liquefied. Anhydrous form shipped as liquefied compressed gas. Soluble in water, alcohol, and ether. Trimethylamine is compressed gas or liquid. Flammable gas. Shipped as a compressed gas, it may be present in an aqueous solution. It has a strong, fishy, ammoniacal odor. The Odor Threshold is 0.00011-0.87 ppm. Warning: The Odor Threshold range is so broad that odor alone should not be used as a warning of potentially hazardous ex
