Monoethanolamine（ETA）

Name: Monoethanolamine（ETA）
SKU: 0

Monoethanolamine (ETA or MEA), with the chemical formula C₂H₇NO, is an important organic chemical raw material. It appears as a colorless, viscous liquid with a mild ammonia-like odor. It is alkaline and hygroscopic, miscible with water, alcohol, etc. in any proportion. The presence of both an amino group and a hydroxyl group in its molecule gives it versatile reactivity, making it widely used in the manufacture of surfactants, gas purification, pharmaceutical and pesticide intermediates, and other fields.
