Triethylene Glycol Dichloride
Triethylene glycol dichloride is a halogenated acyclic ether derivative of polyhydric alcohols, specifically 2,2'-dichlorodiethyl ether (ClCH2CH2OCH2CH2OCH2CH2Cl). It falls under HTS 2909.19.30.00 as it matches the exact description of ethers of polyhydric alcohols that are halogenated derivatives. This chemical is used primarily as a solvent and intermediate in organic synthesis.
Diethylene Glycol Dichloride
Diethylene glycol dichloride (ClCH2CH2OCH2CH2Cl) is a halogenated derivative of polyhydric alcohol ethers, structurally analogous to triethylene glycol dichloride. Classified under HTS 2909.19.30.00 as it represents ethers of polyhydric alcohols with halogen substitution. Used in polymer processing and as a crosslinking agent.
Triethylene Glycol Dichloride Technical Grade 98%
Technical grade triethylene glycol dichloride (98% purity) contains minor impurities but remains a separate chemically defined compound per Chapter 29 Note 1(a). Classified in HTS 2909.19.30.00 as the principal ether structure with halogenation is unchanged. Supplied for industrial solvent applications.
Triethylene Glycol Bis(2-chloroethyl) Ether Stabilized
Stabilized triethylene glycol dichloride with added anti-oxidant preservative, permitted under Chapter 29 Note 1(f). Remains classified HTS 2909.19.30.00 as stabilizer doesn't change essential character. Used in polyurethane resin manufacturing.
