N-(2-Hydroxyethyl)-N-methyl Perfluorooctane Sulfonamide
This is a specific perfluorinated sulfonamide compound with the chemical formula featuring a perfluorooctane chain attached to a sulfonamide group substituted with N-methyl and N-(2-hydroxyethyl) groups. It falls under HTS 2935.40.00.00 as a chemically defined organic sulfonamide per the chapter notes for Chapter 29. Primarily used as a fluorosurfactant intermediate in industrial applications.
Perfluorooctanesulfonamide (PFOSA) Hydroxyethyl Derivative
A derivative of perfluorooctanesulfonic acid amidated with N-methyl-N-(2-hydroxyethyl), this sulfonamide is a key building block for fluoropolymers. Classified under HTS 2935.40.00.00 as it matches the exact subheading for this chemically defined sulfonamide. Used in synthesis of surfactants and coatings.
MeFOSE - Methyl Perfluorooctanesulfonamidoethanol
Commonly abbreviated as MeFOSE, this is N-(2-hydroxyethyl)-N-methyl-1-perfluorooctanesulfonamide, a fluorochemical intermediate. It precisely matches HTS 2935.40.00.00 for this named sulfonamide. Applied in producing water/oil repellents for textiles.
N-Methyl-N-(2-Hydroxyethyl) Perfluorooctyl Sulfonamide
This perfluoroalkyl sulfonamide features a C8 fluorocarbon chain and hydroxyethyl substitution, fitting HTS 2935.40.00.00 exactly. It's a separate chemically defined compound used in polymer modification and surface treatments.
Hydroxyethyl Methyl PFOS Amide
A sulfonamide derivative from perfluorooctanesulfonyl fluoride, with N-substituents methyl and 2-hydroxyethyl. Directly covered by HTS 2935.40.00.00 as the specified compound. Serves as precursor for fluoroacrylate polymers.
