2928.00.15.00 - Phenylhydrazine

This HTS subheading specifically covers Phenylhydrazine, an organic derivative of hydrazine. Phenylhydrazine is characterized by its chemical structure, consisting of a hydrazine group attached to a phenyl ring. Its primary use is as a reagent in organic chemistry, particularly for the detection and characterization of aldehydes and ketones through the formation of phenylhydrazones.

It is important to distinguish Phenylhydrazine from its sibling category, 2928.00.10.00, which covers Methyl ethyl ketoxime. While both are organic derivatives of hydrazine, Phenylhydrazine's classification is based on the presence of the phenyl group, differentiating it from ketoximes. The "Other" sibling category encompasses remaining organic derivatives of hydrazine or hydroxylamine not specifically enumerated.

As this is a leaf node, there are no further subcategories under 2928.00.15.00. Classification within this code is determined by the precise chemical identity of the imported substance as Phenylhydrazine, often confirmed by chemical analysis or supplier documentation.
