2922.50.07.00 - 3,4-Diaminophenetole dihydrogen sulfate; 2-Nitro-5-[(2,3-dihydroxy) propoxy]-N- methyl aniline; 2-Nitro-5-(2-hydroxy ethoxy)-N-methyl aniline; 4-(2-Hydroethoxy)-1,3-phenylene diamine dihydro chloride; 3-Methoxy-4-[(2-hydroxy ethyl) amino] nitro- benzene; 4-[(2-Hydroxy ethyl) amino]-3-nitro phenol; and (R)-α-Amino-4-hydroxy benzene acetic acid (d(-)-p-Hydroxy phenyl glycine)

This HTS category, 2922.50.07.00, encompasses a specific group of aromatic amino compounds characterized by the presence of both amino and oxygen-containing functional groups, particularly phenols and their derivatives. The listed substances, such as 3,4-Diaminophenetole dihydrogen sulfate and various nitroanilines and phenols with hydroxylated alkoxy substituents, are defined by their complex organic structures. These compounds typically find application as intermediates in the synthesis of dyes, pharmaceuticals, or other specialized organic chemicals.

Crucially, this classification is distinguished from its sibling category 2922.50.10.00, which covers different specific aromatic amino compounds including dl-3-(3,4-Di hydroxy phenyl) alanine and N-Ethyl-N-(2-methoxy carbonyl ethyl) aniline, as well as certain toluidine derivatives. Furthermore, it differs from 2922.50.11.00, which is exclusively dedicated to salts of d(-)-p-Hydroxyphenylglycine. The remaining sibling, "Other," serves as a residual category for aromatic amino compounds with oxygen function not otherwise specified.

As a leaf node within the HTS structure, category 2922.50.07.00 does not have any subcategories. Therefore, the focus for classification within this specific code rests on accurately identifying the goods against the detailed descriptions provided for each listed chemical substance. The presence of the amino, phenol, and specific oxygenated side chains, as described, are the primary determinants for classification under this heading.
