2-Anthracenesulfonic acid
2-Anthracenesulfonic acid is a sulfonated derivative of anthracene, a polycyclic aromatic hydrocarbon, containing only sulfo groups as required by HTS 2904. It is a chemically defined organic compound used primarily as an intermediate in dye synthesis and analytical chemistry. This classification falls under heading 2904 for sulfonated hydrocarbons without halogenation or other functional groups.
Sodium 2-Anthracenesulfonate
Sodium 2-anthracenesulfonate is the sodium salt of 2-anthracenesulfonic acid, classified with the parent acid per Chapter 29 note on inorganic salts of organic acids. It serves as a water-soluble intermediate for fluorescent dyes and surfactants. This fits HTS 2904.10.0400 as a derivative containing only sulfo groups.
Ethyl 2-Anthracenesulfonate
Ethyl 2-anthracenesulfonate is the ethyl ester of 2-anthracenesulfonic acid, explicitly covered under HTS 2904 for sulfo derivatives and their ethyl esters. Used in organic synthesis for protecting groups and dye precursors. Chapter notes confirm esters classify with the parent acid-function compound.
2-Anthracenesulfonic acid hydrate
2-Anthracenesulfonic acid hydrate is the parent compound dissolved in water as allowed under Chapter 29 note (d) for chemically defined products. It maintains classification in HTS 2904.10.0400 as a sulfonated hydrocarbon derivative. Commonly used in hydrated form for stability in lab applications.
Purified 2-Anthracenesulfonic acid (98% purity)
High-purity 2-anthracenesulfonic acid (98%) is a refined version of the sulfonated anthracene derivative, free of significant impurities per Chapter 29 scope. Classified under HTS 2904.10.0400 for its sulfo-only hydrocarbon structure. Ideal for precise analytical and synthetic uses.
2-Anthracenesulfonic acid with anticaking stabilizer
This form includes an anticaking agent necessary for preservation/transport, explicitly allowed under Chapter 29 note (f), retaining HTS 2904.10.0400 classification. The stabilizer does not alter its primary sulfo hydrocarbon nature. Used in industrial dye manufacturing.
