2935.30.00.00 - N-Ethyl -N-(2-hydroxyethyl)perfluorooctane sulfonamide

This HTS classification covers N-Ethyl-N-(2-hydroxyethyl)perfluorooctane sulfonamide. This specific chemical compound is characterized by the presence of both an ethyl group and a 2-hydroxyethyl group attached to the nitrogen atom of the perfluorooctane sulfonamide structure. Its unique chemical configuration dictates its application and properties within the broader category of sulfonamides.

Distinguishing this entry from its siblings is crucial for accurate classification. While other perfluorooctane sulfonamides at this level might feature different substituents on the nitrogen atom (e.g., solely methyl or ethyl groups, or other hydroxyethyl substitutions), this category is specifically reserved for the compound where both an ethyl and a 2-hydroxyethyl group are present. For instance, 2935.20.00.00 covers N-Ethyl perfluorooctane sulfonamide, which lacks the 2-hydroxyethyl substituent present here. Similarly, 2935.40.00.00 covers N-(2-hydroxyethyl)-N-methyl perfluorooctane sulfonamide, differing in the presence of a methyl group instead of an ethyl group alongside the 2-hydroxyethyl group.

As this HTS classification is a leaf node, there are no further subdivisions. Classification under 2935.30.00.00 is therefore definitive once the specific chemical identity of N-Ethyl-N-(2-hydroxyethyl)perfluorooctane sulfonamide is confirmed. Practical classification relies on verifying the chemical structure through analytical methods or product documentation.
