Products classified under HTS 2904.36.00.00
Perfluorooctane Sulfonyl Fluoride (PFOSF)
Perfluorooctane sulfonyl fluoride (PFOSF) is a perfluorinated organic compound with the formula C8F17SO2F, classified under HTS 2904.36.00.00 as a sulfonated and halogenated derivative of hydrocarbons. It serves as a key intermediate in synthesizing perfluorooctane sulfonic acid salts and other fluorochemicals used in surface treatments.
99% Pure PFOSF Technical Grade
Technical grade perfluorooctane sulfonyl fluoride at 99% purity, a fluorinated sulfonyl compound under HTS 2904.36.00.00 due to its perfluorinated structure and sulfonyl fluoride functional group. Used primarily as a synthetic precursor for PFOS-based surfactants in industrial applications.
Perfluorooctane Sulfonyl Fluoride with Stabilizer
Stabilized perfluorooctane sulfonyl fluoride containing added inhibitors for transport safety, still classified under HTS 2904.36.00.00 per Chapter 29 note (f) allowing stabilizers. The core compound remains the chemically defined C8F17SO2F used in fluoropolymer manufacturing.
Industrial PFOSF for Surfactant Synthesis
High-volume industrial grade perfluorooctane sulfonyl fluoride specifically for conversion to PFOS surfactants, classified under HTS 2904.36.00.00 as a perfluorinated sulfonyl fluoride. Meets Chapter 29 requirements for chemically defined halogenated sulfonated hydrocarbons.
PFOSF Anhydrous Reagent Grade
Anhydrous reagent-grade perfluorooctane sulfonyl fluoride for laboratory synthesis of fluorinated compounds, under HTS 2904.36.00.00 for its sulfonated, perfluorinated structure. Supplied in small quantities with high purity specifications.
Distilled Perfluorooctane Sulfonyl Fluoride
Vacuum-distilled perfluorooctane sulfonyl fluoride achieving ultra-high purity (>99.5%), classified under HTS 2904.36.00.00 as the pure sulfonyl fluoride derivative. Used in precision fluorochemical manufacturing processes.
PFOSF with Emetic Identifier
Perfluorooctane sulfonyl fluoride with trace emetic additive for safety identification, permitted under HTS 2904.36.00.00 per Chapter 29 note (g). The addition facilitates hazard recognition without changing general chemical use.
