Products classified under HTS 2902.19.00.50
Norbornane
Norbornane is a bridged cyclic hydrocarbon (C7H12) classified as a cyclane under HTS 2902.19.0050 due to its saturated bicyclic structure with no aromatic characteristics. It serves as a key intermediate in organic synthesis and pharmaceutical production.
Cycloheptane
Cycloheptane (C7H14) is a seven-membered saturated cycloalkane used as a solvent and reaction medium in chemical manufacturing. It qualifies under HTS 2902.19.0050 as a cyclane, being a non-aromatic cyclic hydrocarbon.
Bicyclo[2.2.1]heptane
Bicyclo[2.2.1]heptane is a saturated bicyclic cyclane used in polymer precursor synthesis and fragrance chemistry. Classified under HTS 2902.19.0050 as it meets criteria for cyclanes other than specified subheadings.
Adamantane
Adamantane (C10H16) is a highly symmetrical tricyclic cyclane used in pharmaceutical intermediates and materials science. It falls under HTS 2902.19.0050 as a complex cyclane structure not specifically enumerated elsewhere.
Perhydroindane
Perhydroindane is a fully saturated bicyclic hydrocarbon (decahydro-1H-indene) used in high-performance lubricant formulations. Classified as 'other cyclanes' under HTS 2902.19.0050 due to its fused ring cyclane structure.
Spiropentane
Spiropentane (C5H8) features two fused cyclopropane rings at a single carbon atom, classifying it as a unique cyclane under HTS 2902.19.0050. Primarily used in advanced organic chemistry research.
Cyclodecane
Cyclodecane (C10H20) is a medium-ring saturated cycloalkane serving as a phase-change material and polymer precursor. It qualifies under HTS 2902.19.0050 as a higher cyclane not specifically provided for.
