Ethylenediamine
Ethylenediamine (EDA), a colorless liquid with the formula H2NCH2CH2NH2, is a separate chemically defined acyclic polyamine. It is a key industrial intermediate used in chelating agents, pharmaceuticals, and polymer curing, and is not excluded by Chapter 29 notes.
2921.21.00Ethylenediamine Dihydrochloride
Ethylenediamine dihydrochloride (C2H8N2·2HCl) is the salt form of ethylenediamine, a white crystalline powder used in pharmaceutical synthesis and polymer curing. As an inorganic salt of an organic compound, it is classified with the parent compound per Chapter 29 Note 5(C)(1).
2921.21.00Ethylenediamine Monohydrate
Ethylenediamine monohydrate is an aqueous solution of ethylenediamine at standard transport concentrations (30-70% EDA). Per Chapter 29 Note 1(d), solutions of chemically defined organic compounds in water are classified in the same heading as the compound itself.
2921.21.00Ethylenediamine Tetraacetic Acid (EDTA) Precursor Grade
High-purity ethylenediamine (EDA) specifically graded for the synthesis of ethylenediamine tetraacetic acid (EDTA) chelants. It is a separate chemically defined acyclic polyamine, meeting Chapter 29 criteria, and is not put up in measured doses or for retail sale.
2921.21.00N-Ethylethylenediamine
N-Ethylethylenediamine is a derivative of ethylenediamine with one amine group mono-substituted by an ethyl group (H2NCH2CH2NHCH2CH3). It remains an acyclic polyamine and, as a derivative of ethylenediamine, is classified in the same subheading per Subheading Note 1, provided it is not more specifically covered elsewhere.
