Products classified under HTS 2921.19.61.95
Diethylenetriamine (DETA)
Diethylenetriamine is an acyclic polyamine with two primary amine groups and one secondary amine group, classified under HTS 2921.19.61.95 as an acyclic monoamine derivative. It is widely used in epoxy curing agents and chelating agents.
N,N-Dimethylethylenediamine
This tertiary amine derivative features an acyclic chain with both primary and tertiary amine functionalities, fitting HTS 2921.19.61.95 for other acyclic monoamine derivatives. Commonly used in pharmaceutical intermediates and polymer synthesis.
3,3'-Iminobis(N,N-dimethylpropylamine) (IBDMA)
IBDMA is a complex acyclic polyamine used in fuel additives and epoxy hardeners, classified under 2921.19.61.95 as it meets criteria for chemically defined acyclic amine derivatives per Chapter 29 note (a).
N-Isopropylethylenediamine
A secondary amine derivative with branched alkyl substitution on acyclic ethylenediamine backbone, properly classified in 2921.19.61.95. Used in synthesis of chelating agents and pharmaceutical APIs.
1,2-Propylenediamine
Propylenediamine features an acyclic propane backbone with two primary amine groups, qualifying under HTS 2921.19.61.95 as other acyclic monoamines. Essential intermediate for chiral ligands and polymers.
