Products classified under HTS 2924.19.80.00
Acetazolamide
Acetazolamide is a carbonic anhydrase inhibitor used primarily as a diuretic and for glaucoma treatment, featuring an acyclic amide structure with a sulfonamide group. It falls under HTS 2924.19.80.00 as an acyclic amide derivative not specifically covered by other subheadings in 2924.19. This classification aligns with chapter notes for chemically defined organic compounds with amide functions.
Lidocaine
Lidocaine is a local anesthetic containing an acyclic amide (diethylamino acetanilide) linkage essential to its pharmacological action. Classified under HTS 2924.19.80.00 as an 'other' acyclic amide derivative, it fits chapter 29 provisions for chemically defined compounds with carboxyamide functions not elsewhere specified.
Bupivacaine Hydrochloride
Bupivacaine hydrochloride is an amide-type local anesthetic with an acyclic carboxamide group, supplied as its hydrochloride salt. Under HTS 2924.19.80.00, the salt classifies with the parent acyclic amide per chapter note 3(C)(1), covering 'other' derivatives.
Mepivacaine
Mepivacaine, a piperidine-based aminoamide anesthetic, contains a key acyclic amide linkage. HTS 2924.19.80.00 covers this as an 'other' acyclic amide, prioritizing amide function over any heterocyclic elements per classification notes.
N,N-Diethylacetamide
N,N-Diethylacetamide is an acyclic tertiary amide used as a solvent and chemical intermediate. Classified in HTS 2924.19.80.00 for other acyclic amides and derivatives, fitting chapter 29's scope for chemically defined compounds.
Formamide
Formamide (HCONH2) is the simplest acyclic amide, used as a solvent and in organic synthesis. HTS 2924.19.80.00 captures it as an 'other' acyclic amide, excluded from more specific subheadings.
N-Methylacetamide
N-Methylacetamide is an acyclic secondary amide employed in peptide synthesis and as a solvent. It properly classifies under HTS 2924.19.80.00 for unspecified acyclic amide derivatives.
Procainamide Hydrochloride
Procainamide hydrochloride, an antiarrhythmic agent, features an acyclic para-aminobenzamide structure with hydrochloride salt. The salt follows the parent amide into HTS 2924.19.80.00 per chapter salt classification rules.
Diethyltoluamide (DEET)
DEET (N,N-diethyl-m-toluamide) is an acyclic tertiary amide widely used as insect repellent. HTS 2924.19.80.00 includes it as an 'other' acyclic carboxamide derivative.
Acetamide
Acetamide (CH3CONH2) is a simple acyclic primary amide used in organic synthesis and as a plasticizer. Classified under HTS 2924.19.80.00 for general acyclic amides.
Lactam (Beta-Propiolactam)
Beta-propiolactam, though strained, functions as an acyclic amide equivalent in reactivity. HTS 2924.19.80.00 accommodates it as an 'other' acyclic amide derivative before potential polymerization.
Methacrylamide
Methacrylamide is an acyclic amide with vinyl functionality, used in polymer production. Falls under HTS 2924.19.80.00 as an unsaturated acyclic amide derivative.
Ethyl Acetamide
Ethyl acetamide (CH3CONHEt) represents N-substituted acyclic amides used in fine chemical synthesis. HTS 2924.19.80.00 covers such general derivatives.
Prilocaine
Prilocaine is an aminoamide anesthetic featuring an acyclic secondary amide group derived from toluidine. It qualifies for HTS 2924.19.80.00 as an unspecified acyclic amide derivative, consistent with chapter provisions for amide-function compounds.
Dimethylacetamide (DMAC)
Dimethylacetamide (DMAC) is a polar aprotic solvent with an acyclic amide structure (N,N-dimethylacetamide). It falls under HTS 2924.19.80.00 as an 'other' acyclic amide, suitable for industrial and pharmaceutical applications per chapter definitions.
