sym-Diethyldiphenylurea
sym-Diethyldiphenylurea is a specific aromatic ureine derivative classified under HTS 2924.21.18.00 as a cyclic amide-function compound of carbonic acid. It appears as a white to off-white crystalline powder primarily used as a chemical intermediate in organic synthesis.
Diethylcarbamoyl Diphenylamine
Also known as diethylcarbamoyl diphenylamine, this is the systematic name for sym-diethyldiphenylurea under HTS 2924.21.18.00. It's a key reagent in dye manufacturing and polymer chemistry, fitting the chapter's definition for chemically defined aromatic ureines.
Uvinul D-49 Stabilizer
Commercial product Uvinul D-49 contains sym-diethyldiphenylurea as active ingredient, used as light stabilizer in plastics. Classified under HTS 2924.21.18.00 when imported as pure chemical, per chapter notes for chemically defined compounds.
sym-Diethyldiphenylurea Flake Form
sym-Diethyldiphenylurea in flake physical form for easier handling in industrial processes, still classified under HTS 2924.21.18.00. Meets chapter note (f) for products with added stabilizers necessary for transport.
sym-Diethyldiphenylurea Technical Grade
Technical grade sym-diethyldiphenylurea (95-98% purity) is an aromatic ureine used in pharmaceutical intermediate production, classified under HTS 2924.21.18.00 due to its specific chemical structure as a di-substituted diphenylurea derivative.
