Products classified under HTS 2925.19.70.00
N-Chlorosuccinimide (NCS)
N-Chlorosuccinimide is a chemically defined cyclic imide derivative used as a chlorinating and oxidizing agent in organic synthesis. It falls under HTS 2925.19.70.00 as a specific imide compound listed in this subheading for carboxyimide-function compounds. Primarily employed in pharmaceutical and fine chemical manufacturing for selective chlorination reactions.
N,N'-Ethylenebis(5,6-Dibromonorbornanedicarboximide)
This is a bis-imide compound featuring two dibromo-norbornane dicarboximide units linked by an ethylene bridge, explicitly named in HTS 2925.19.70.00. Used as a brominating agent and flame retardant intermediate in polymer chemistry. Qualifies as a derivative of imides under chapter 29 carboxyimide-function compounds.
99% Pure N-Chlorosuccinimide Powder
High-purity N-chlorosuccinimide in powdered form for laboratory and industrial synthesis, containing minor impurities but remains chemically defined. Specifically listed under HTS 2925.19.70.00 as an imide derivative not excluded by chapter notes on impurities. Common in alpha-chlorination of pharmaceuticals and natural product synthesis.
N-Chlorosuccinimide with Stabilizer Additive
N-Chlorosuccinimide formulated with minimal anticaking stabilizer for safe transport and storage, compliant with chapter note (f). Remains classified under HTS 2925.19.70.00 as the principal imide compound with necessary preservative. Used in bulk for continuous flow chlorination processes.
