Products classified under HTS 2922.50.35.00
Lidocaine Hydrochloride
Lidocaine hydrochloride is an aromatic amino-compound with oxygen function, specifically a local anesthetic derived from xylidine, classified under HTS 2922.50.3500 as per additional U.S. note 3 to section VI for certain pharmaceutical intermediates. It features an amino group and ether oxygen function on an aromatic ring, fitting the chapter's criteria for oxygen-function amino-compounds.
Bupivacaine Hydrochloride
Bupivacaine hydrochloride is an aromatic amino-compound featuring amide oxygen function and amino group, used as a long-acting local anesthetic intermediate under HTS 2922.50.3500 per U.S. note 3. Its structure aligns with chapter notes for oxygen-function amino-compounds on benzene rings.
Procaine Hydrochloride
Procaine hydrochloride, or novocaine, is a p-aminobenzoic acid ester with amino and phenolic oxygen functions, an aromatic compound listed under HTS 2922.50.3500 via U.S. note 3 for local anesthetics. It qualifies as an amino-acid-phenol per chapter definitions.
Prilocaine Hydrochloride
Prilocaine hydrochloride is an ortho-toluidine derivative with amino and amide oxygen functions, classified as an aromatic oxygen-function amino-compound under HTS 2922.50.3500 per additional note 3. Used primarily as a local anesthetic base.
Mepivacaine Hydrochloride
Mepivacaine hydrochloride features an N-methyl-pipecoloxylidide structure with aromatic amino and amide oxygen, fitting HTS 2922.50.3500 for note 3 products as anesthetic intermediates. Chapter notes confirm classification by latest numerical heading.
Articaine Hydrochloride
Articaine hydrochloride is a thiophene-based aromatic amino-amide with sulfonate oxygen function, included in HTS 2922.50.3500 under U.S. note 3 for dental anesthetics. Its structure qualifies as amino-compound with oxygen function per chapter scope.
Chloroprocaine Hydrochloride
Chloroprocaine hydrochloride is a chlorinated p-aminobenzoic acid ester, an aromatic amino-acid-phenol with ester oxygen, under HTS 2922.50.3500 via note 3 for short-acting anesthetics. Fits chapter notes for halogenated oxygen-function amino-compounds.
