Products classified under HTS 2928.00.15.00
Phenylhydrazine
Phenylhydrazine is a chemically defined organic derivative of hydrazine, consisting of a phenyl group attached to the hydrazine moiety (C6H5NHNH2). It falls under HTS 2928.00.15.00 as a specific compound within the heading for organic derivatives of hydrazine or hydroxylamine. Primarily used in organic synthesis and analytical chemistry.
4-Nitrophenylhydrazine
4-Nitrophenylhydrazine is a nitrated derivative of phenylhydrazine, a chemically defined organic compound under HTS 2928.00.15.00. The nitro group is integral to its structure as a hydrazine derivative, used in carbonyl compound derivatization.
2,4-Dinitrophenylhydrazine
2,4-Dinitrophenylhydrazine (DNPH) is a dinitrated phenylhydrazine derivative, chemically defined and used for aldehyde/ketone detection. Classifies under HTS 2928.00.15.00 as hydrazine derivative with permitted nitrated substituents.
Phenylhydrazine Hydrochloride
Phenylhydrazine hydrochloride is the hydrochloride salt of phenylhydrazine, a chemically defined organic hydrazine derivative. Classified under HTS 2928.00.15.00 per Chapter note on salts of organic compounds following the parent hydrazine structure. Commonly used in osazone formation for carbohydrate analysis.
Phenylhydrazine Stabilized with Acetic Acid
Phenylhydrazine stabilized with a minimal amount of acetic acid to prevent oxidation, remaining a chemically defined hydrazine derivative under HTS 2928.00.15.00. The stabilizer is necessary for preservation per Chapter note (f).
