Products classified under HTS 2933.32.50.00
Piperidine Hydrochloride
Piperidine hydrochloride is the salt form of piperidine, a heterocyclic compound containing an unfused piperidine ring, classified under HTS 2933.32.5000 as 'other' piperidine and its salts. It is commonly used as a chemical intermediate in pharmaceutical synthesis and as a catalyst in organic reactions.
4-Aminopiperidine Dihydrochloride
4-Aminopiperidine dihydrochloride is a substituted piperidine salt used in synthesis of pharmaceutical intermediates like antihistamines. It features the core piperidine ring structure required for HTS 2933.32.5000 classification as 'other' piperidine salts.
1-Methylpiperidine
1-Methylpiperidine is an N-alkylated derivative of piperidine, a saturated six-membered heterocyclic amine fitting HTS 2933.32.5000 as 'other' piperidine compounds. Used as a base in organic synthesis and solvent in chemical manufacturing.
Piperidine-4-Carboxylic Acid
Piperidine-4-carboxylic acid (isonipecotic acid) contains both piperidine ring and carboxylic acid functionality but classifies under HTS 2933.32.5000 per Chapter 29 notes prioritizing heterocyclic structure. Used in synthesis of protease inhibitors.
4-Phenylpiperidine Hydrochloride
4-Phenylpiperidine hydrochloride is a key intermediate for opioid analgesics like pethidine (meperidine). The core piperidine ring structure qualifies it for HTS 2933.32.5000 as 'other' piperidine salt despite phenyl substitution.
1-Benzylpiperidine
1-Benzylpiperidine is an N-protected piperidine derivative used in medicinal chemistry. Its unfused piperidine ring structure places it under HTS 2933.32.5000 as 'other' piperidine compound, not classified by benzyl group per Chapter notes.
Piperidine-1-Carboxylic Acid tert-Butyl Ester
Boc-piperidine (piperidine-1-carboxylic acid tert-butyl ester) is a protected piperidine used in peptide synthesis. Classifies under HTS 2933.32.5000 as the ester follows parent piperidine per Chapter 29 ester classification rules.
4-Piperidone Hydrochloride Monohydrate
4-Piperidone hydrochloride monohydrate is a cyclic ketone derivative of piperidine used in alkaloid synthesis. The piperidine ring structure dominates classification under HTS 2933.32.5000 as 'other' piperidine salt.
1-(2-Methoxyethyl)piperidine
1-(2-Methoxyethyl)piperidine is an ether-substituted piperidine used as a synthetic intermediate. Its core piperidine structure qualifies for HTS 2933.32.5000 classification as 'other' piperidine compound.
3,5-Dimethylpiperidine
3,5-Dimethylpiperidine is a dialkylated piperidine derivative used in chiral ligand synthesis. As a simple substituted piperidine, it falls under HTS 2933.32.5000 'other' category.
