Classified under HTS 2925.19.91.00 as an 'other' imide not specifically provided for in prior subheadings. Used in synthesis of pharmaceuticals like ethosuximide and as a reagent in organic chemistry.
Glutarimide
Glutarimide is a six-membered cyclic imide derived from glutaric acid, a carboxyimide-function compound. Falls under HTS 2925.19.91.00 as 'other' imides; used in production of pharmaceuticals like thalidomide analogs and as a corrosion inhibitor.
Maleimide
Maleimide is an unsaturated five-membered cyclic imide with a reactive double bond, used in polymer chemistry and bioconjugation. Classified in HTS 2925.19.91.00 as a derivative imide; the imide function determines classification over unsaturation.
N-Phenylmaleimide
N-Phenylmaleimide is an N-substituted derivative of maleimide with a phenyl group on nitrogen, used in high-performance polymer synthesis. HTS 2925.19.91.00 covers this substituted imide as 'other' derivatives; aryl substitution doesn't change heading.
Diphenylmaleimide
Diphenylmaleimide features two phenyl groups on the imide nitrogen, used in specialty resins and electronics. As a substituted cyclic imide derivative, it properly classifies under HTS 2925.19.91.00 'other' imides.
