Carbon Tetrachloride
Carbon tetrachloride (CCl4) is a saturated chlorinated derivative of the acyclic hydrocarbon methane, with all four hydrogen atoms replaced by chlorine. It falls under HTS 2903.19.60 as a halogenated derivative of hydrocarbons that is neither chloroform nor specified dichloromethane derivatives. This colorless, non-flammable liquid was historically used as a solvent and in fire extinguishers.
1,1,1-Trichloroethane
1,1,1-Trichloroethane (CH3CCl3) is a saturated chlorinated derivative of ethane with three chlorine atoms on one carbon. Classified under HTS 2903.19.60 as 'other' saturated chlorinated acyclic hydrocarbons, excluding specific isomers. Commonly used as a degreasing agent and dry cleaning solvent before phase-out under Montreal Protocol.
1,1,2-Trichloroethane
1,1,2-Trichloroethane (CH2ClCHCl2) is a saturated chlorinated acyclic hydrocarbon with chlorine atoms distributed across both carbons of the ethane chain. It qualifies for HTS 2903.19.60 as it is not a specifically enumerated derivative. Used as a chemical intermediate and solvent in organic synthesis.
Pentachloroethane
Pentachloroethane (C2HCl5) is a highly chlorinated saturated derivative of ethane containing five chlorine atoms. Falls under HTS 2903.19.60 as 'other' saturated chlorinated acyclic hydrocarbons. Used as a refrigerant intermediate and in specialty solvent applications.
Hexachloroethane
Hexachloroethane (C2Cl6), also known as perchloroethane, is the fully chlorinated saturated derivative of ethane. Classified under HTS 2903.19.60 as it represents 'other' saturated chlorinated acyclic hydrocarbons not specifically enumerated. Primarily used in pyrotechnics, smoke compositions, and alloy production.
