Products classified under HTS 2916.39.04.00
m-Chloroperoxybenzoic Acid (mCPBA) 75% Technical Grade
m-Chloroperoxybenzoic acid (mCPBA) is a peroxyacid used primarily as an oxidizing agent in organic synthesis for epoxidation reactions and Baeyer-Villiger oxidations. This 75% technical grade product, typically stabilized with water and a wetting agent, falls under HTS 2916.39.04.00 as it is specifically listed as an aromatic peroxyacid derivative.
m-Chloroperoxybenzoic Acid (mCPBA) 70-77% Min. Lab Grade
Laboratory-grade mCPBA with minimum 70-77% purity is used for precise organic oxidations in research settings, particularly for converting alkenes to epoxides. Classified under HTS 2916.39.04.00 due to its explicit identification as m-chloroperoxybenzoic acid, an aromatic peroxyacid.
p-Sulfobenzoic Acid Potassium Salt
p-Sulfobenzoic acid potassium salt is an aromatic sulfonic acid derivative used as an intermediate in dye manufacturing and pharmaceutical synthesis. It qualifies for HTS 2916.39.04.00 as it is explicitly named in the tariff description for aromatic monocarboxylic acid sulfonated derivatives.
mCPBA 77% with 23% Water Stabilizer
This stabilized formulation contains 77% m-chloroperoxybenzoic acid with 23% water as per chapter note (d), preventing explosive decomposition. Used in industrial epoxidation processes, it remains classified under HTS 2916.39.04.00 as the water dissolution is solely for safety/transport.
3-Chloroperoxybenzoic Acid Analytical Standard
High-purity analytical standard of m-chloroperoxybenzoic acid used for calibration in chromatography and spectroscopic analysis. Falls under HTS 2916.39.04.00 as a separate chemically defined aromatic peroxyacid meeting chapter note (a).
Potassium 4-Sulfobenzoate
Potassium 4-sulfobenzoate (p-sulfobenzoic acid potassium salt) serves as a reactive intermediate in azo dye coupling and sulfonated drug synthesis. Specifically listed under HTS 2916.39.04.00 among aromatic monocarboxylic acid sulfonated derivatives.
mCPBA Max Safety Stabilized Grade
Commercial mCPBA grade with proprietary stabilizers (per chapter note f) for safe bulk handling in continuous manufacturing processes. Retains HTS 2916.39.04.00 classification as stabilizer addition is necessary solely for preservation/transport.
