Nitrobenzene
Nitrobenzene is a pale yellow liquid organic compound with the formula C6H5NO2, produced by nitration of benzene. It falls under HTS 2904.20.5000 as a sulfonated/nitrated derivative of hydrocarbons containing only nitro groups, used primarily as an intermediate in aniline production. This classification applies to pure nitrobenzene not covered by more specific subheadings.
Nitromethane
Nitromethane (CH3NO2) is a simple nitroalkane used as a solvent, fuel additive, and chemical intermediate. It qualifies under HTS 2904.20.5000 as a nitrated derivative of hydrocarbons (methane) containing only nitro groups. Chapter notes confirm acyclic nitro compounds belong here.
2-Nitrotoluene
2-Nitrotoluene (o-nitrotoluene, C7H7NO2) is an isomeric nitro derivative of toluene used in explosives and dyes. Falls under HTS 2904.20.5000 as 'other' nitrated aromatic hydrocarbon with single nitro group. Distinguished from dinitro derivatives.
