Import Tips & Compliance
• Validate branched structure with molecular formula C4H9ClO documentation
• Monitor for peroxide formation; include inhibitor certificates if stabilized
• Avoid bulk packaging over 30L drums to prevent 'preparations' reclassification

2-Chloroethanol
2-Chloroethanol is a halogenated derivative of ethanol, featuring a chlorine atom attached to the carbon chain of an acyclic alcohol. It falls under HTS 2905.59.90.00 as a halogenated acyclic alcohol derivative, distinct from simpler monohalogenated compounds like chlorohydrins specified elsewhere in the subheading. Commonly used as a chemical intermediate in pharmaceutical and pesticide manufacturing.
2-Bromoethanol
2-Bromoethanol is a brominated acyclic alcohol derivative used in organic synthesis and as a pharmaceutical intermediate. Classified under HTS 2905.59.90.00 as 'other' halogenated derivatives of acyclic alcohols, separate from ethylene chlorohydrin provisions. Its structure maintains the characteristic alcohol group with halogen substitution.
1-Nitropropan-2-ol
1-Nitropropan-2-ol is a nitrated derivative of propanol, featuring a nitro group on the acyclic alcohol chain. It qualifies for HTS 2905.59.90.00 as an 'other' nitrated acyclic alcohol derivative used in explosive and pharmaceutical synthesis. The nitro functionality clearly identifies it within this subheading's scope.
3-Chloropropan-1-ol
3-Chloropropan-1-ol serves as a versatile intermediate in polymer and pharmaceutical production, characterized by chlorine substitution on a propane alcohol chain. HTS 2905.59.90.00 covers this as 'other' halogenated acyclic alcohol derivatives beyond basic chlorohydrins. Its primary alcohol function governs classification.
2-Nitroethanol
2-Nitroethanol is a nitrated ethanol derivative used in nitrocellulose manufacturing and organic synthesis. It fits HTS 2905.59.90.00 as an 'other' nitrosated/nitrated acyclic alcohol, maintaining ethanol's acyclic structure with nitro substitution. Excluded from exclusions like Chapter 29 note 2(d) inorganic carbons.
2-Fluoroethanol
2-Fluoroethanol represents a fluorinated acyclic alcohol derivative employed in positron emission tomography (PET) tracer synthesis. HTS 2905.59.90.00 includes this as 'other' halogenated (fluorine qualifies) acyclic alcohol per Chapter 29 note 4. Its high reactivity stems from the C-F bond adjacent to OH.
