2922.49.05.00 - (R)-α-Aminobenzeneacetic acid; 2-Amino-3-chlorobenzoic acid, methyl ester

This HTS category, 2922.49.05.00, specifically covers certain aromatic amino-acids and their methyl esters that do not fit into the more narrowly defined subcategories. The included substances are (R)-α-Aminobenzeneacetic acid and 2-Amino-3-chlorobenzoic acid, methyl ester. These are complex organic molecules characterized by the presence of both an amino group and a carboxylic acid derivative (ester in this case) attached to an aromatic ring structure.

Distinct from its sibling category 2922.49.10.00, which enumerates a specific list of common aromatic amino-acids and their derivatives, this category serves as a residual for other aromatic amino-acid derivatives that do not meet those explicit listings. The key differentiator lies in the precise chemical structure and the absence of specific naming conventions within the more granular sibling. While both fall under "Aromatic: Other" amino-acids, this particular node is for unlisted or less common aromatic amino-acid derivatives.

As this is a leaf node, there are no further subcategories to introduce. Classification into this specific HTS code hinges on the accurate identification of the chemical compound and its confirmation as an aromatic amino-acid derivative that is not specifically detailed in other sibling categories at this level. Therefore, detailed chemical analysis and comparison against the enumerated substances in related codes are paramount for correct classification.
