Products classified under HTS 2902.90.40.00
Anthracene Powder (99% Purity)
Anthracene is a solid polycyclic aromatic hydrocarbon (C14H10) classified under HTS 2902.90.40.00 as a specific cyclic hydrocarbon. It appears as colorless to pale yellow powder and is a key intermediate in organic synthesis. This pure form meets chapter 29 note (a) for separate chemically defined organic compounds.
Sublimed Anthracene Crystals
Sublimed anthracene crystals are highly purified anthracene (C14H10) obtained via sublimation, specifically named in HTS 2902.90.40.00 as a cyclic hydrocarbon. Used in scintillator production and organic electronics. Qualifies under chapter notes for chemically defined compounds without excluded additives.
1,4-Di-(2-methylstyryl)benzene (CAS 6383-95-5)
1,4-Di-(2-methylstyryl)benzene is a stilbene derivative specifically listed under HTS 2902.90.40.00 as a cyclic hydrocarbon. This fluorescent compound (C24H24) is used in optical brighteners and laser dyes. Fits Chapter 29 for pure organic compounds, excluding coloring matter exclusions.
Research-Grade Anthracene (ACS Reagent)
ACS reagent-grade anthracene meets American Chemical Society standards for lab use, classified under HTS 2902.90.40.00 due to its specific naming as a cyclic hydrocarbon. Purity exceeds 99.5% with low ash/impurity specs. Adheres to Chapter 29 for chemically defined compounds.
