Products classified under HTS 2909.19.60.00
Diethylene Glycol Diethyl Ether
Diethylene glycol diethyl ether is an acyclic ether derived from the polyhydric alcohol diethylene glycol, where both hydroxyl groups are etherified with ethyl groups. It falls under HTS 2909.19.60.00 as an 'other' ether of a polyhydric alcohol, chemically defined and not specifically excluded by chapter notes. Commonly used as a solvent in industrial applications.
Triethylene Glycol Dimethyl Ether
Triethylene glycol dimethyl ether (triglyme) is an acyclic diether from the polyhydric alcohol triethylene glycol etherified with methyl groups. Classified in HTS 2909.19.60.00 as an 'other' ether of polyhydric alcohol per Chapter 29 notes on chemically defined organic compounds. Used in organic synthesis and as a coordinating solvent.
Pentaerythritol Tetraethyl Ether
Pentaerythritol tetraethyl ether is a tetrafunctional acyclic ether derived from the tetrahydric alcohol pentaerythritol fully etherified with ethyl groups. It qualifies under HTS 2909.19.60.00 as an ether of polyhydric alcohol, meeting Chapter 29 requirements for separate chemically defined compounds. Used in specialty resins and coatings.
Dipropylene Glycol Methyl Ether
Dipropylene glycol methyl ether (DPGME) is an acyclic monoether from the polyhydric alcohol dipropylene glycol. Classified in HTS 2909.19.60.00 as other ether of polyhydric alcohol, not the ethylene glycol-specific subheading. Widely used as coalescing aid in waterborne coatings.
Sorbitol Hexaethyl Ether
Sorbitol hexaethyl ether is the fully perethylated derivative of hexahydric sorbitol, creating six ethyl ether linkages. Meets HTS 2909.19.60.00 criteria as chemically defined acyclic ether of polyhydric alcohol per Chapter 29 notes. Used in carbohydrate chemistry research.
1,3-Propanediol Di-n-butyl Ether
1,3-Propanediol di-n-butyl ether features two butyl ether groups on the dihydric 1,3-propanediol backbone. Classified under HTS 2909.19.60.00 as acyclic ether of polyhydric alcohol, chemically defined organic compound. Functions as green solvent alternative.
Neopentyl Glycol Diisobutyl Ether
Neopentyl glycol diisobutyl ether derives from dihydric neopentyl glycol with two isobutyl ether moieties. Falls in HTS 2909.19.60.00 as other acyclic polyhydric alcohol ether per Chapter 29 chemical definition. Used in polymer plasticizers.
Trimethylolpropane Triethyl Ether
Trimethylolpropane triethyl ether is the triether derivative of trihydric trimethylolpropane. Qualifies for HTS 2909.19.60.00 as chemically defined acyclic ether of polyhydric alcohol. Applied in alkyd resin modification.
Polyethylene Glycol Di-n-propyl Ether (PEG-400)
PEG-400 di-n-propyl ether has propylene ether termini on poly(ethylene glycol) 400 chain. While PEG ethers often fall in 2909.19.20, this propyl derivative classified as 'other' in HTS 2909.19.60.00. Used in drug delivery formulations.
1,4-Butanediol Dimethyl Ether
1,4-Butanediol dimethyl ether (BDE) features methyl ethers on both ends of dihydric 1,4-butanediol. Classified HTS 2909.19.60.00 as acyclic polyhydric alcohol ether, chemically defined. Alternative diesel fuel additive.
Ethoxydiglycol (Diethylene Glycol Monoethyl Ether)
Ethoxydiglycol is monoetherified diethylene glycol with one ethyl ether and one free hydroxyl. As ether of polyhydric alcohol, falls in HTS 2909.19.60.00 'other' category. Cosmetic solvent and penetration enhancer.
Propylene Glycol Diethyl Ether
Propylene glycol diethyl ether is the diether of 1,2-propanediol with two ethyl groups. HTS 2909.19.60.00 as other acyclic polyhydric alcohol ether, not ethylene glycol specific. Used in ink formulations.
Butynediol Butyl Ether
2-Butynediol monobutyl ether retains one free OH and one butyl ether on dihydric butynediol. Acyclic ether-alcohol of polyhydric alcohol for HTS 2909.19.60.00. Specialty intermediate with acetylenic functionality.
