Products classified under HTS 2922.17.00.00
Methyldiethanolamine (MDEA)
Methyldiethanolamine (MDEA) is a tertiary amino alcohol with the chemical formula CH3N(CH2CH2OH)2, classified under HTS 2922.17.00.00 as a specific oxygen-function amino-alcohol compound. It is a colorless viscous liquid used primarily in industrial applications for gas sweetening and chemical synthesis.
Ethyldiethanolamine (EDEA)
Ethyldiethanolamine (EDEA), with formula C2H5N(CH2CH2OH)2, is a tertiary amino alcohol explicitly listed under HTS 2922.17.00.00 as an oxygen-function amino-compound. This clear liquid serves as a chemical intermediate in pharmaceutical and surfactant production.
Purified Methyldiethanolamine 99% Technical Grade
High-purity methyldiethanolamine (99% min) is a chemically defined tertiary amino alcohol under HTS 2922.17.00.00, meeting Chapter 29 note (a) for separate organic compounds. Used in natural gas purification to remove H2S and CO2.
