Products classified under HTS 2930.90.92.22
N,N-Dipropylaminoethane-2-thiol
This is a specific organo-sulfur compound featuring a n-propyl dialkyl substitution on the nitrogen atom of the aminoethane-2-thiol structure. It falls under HTS 2930.90.92.22 as it matches the exact chemical definition for N,N-dialkyl (methyl, ethyl, n-propyl or isopropyl) aminoethane-2-thiols, excluding the dimethyl and diethyl variants. Used primarily as an intermediate in pharmaceutical synthesis and as a reagent in organic chemistry.
2-(N,N-Diisopropylamino)ethanethiol
An organo-sulfur compound with isopropyl groups on the nitrogen atom, specifically 2-(N,N-diisopropylamino)ethanethiol. Classified under HTS 2930.90.92.22 due to its aminoethane-2-thiol structure with permitted isopropyl dialkyl substitution, excluded only dimethyl/diethyl forms. Commonly used in synthesis of thioether ligands and pharmaceutical precursors.
N-Ethyl-N-isopropylaminoethane-2-thiol
Mixed dialkyl substituted aminoethane-2-thiol with ethyl and isopropyl groups on nitrogen. Qualifies for HTS 2930.90.92.22 as it uses permitted alkyl groups (ethyl, isopropyl) in the N,N-dialkyl aminoethane-2-thiol definition, excluding only specific dimethyl/diethyl. Applied in metal chelation chemistry and drug development.
N,N-Di(n-propyl)aminoethanethiol Hydrochloride
Protonated salt form of N,N-di(n-propyl)aminoethane-2-thiol hydrochloride. Explicitly covered under HTS 2930.90.92.22 which includes protonated salts of specified aminoethane-2-thiols (excluding dimethyl/diethyl). Used in aqueous formulations for biochemical research.
2-(N-Methyl-N-ethylamino)ethanethiol
Mixed methyl-ethyl substituted aminoethane-2-thiol, a chemically defined organo-sulfur compound. Fits HTS 2930.90.92.22 criteria using permitted dialkyl groups (methyl, ethyl) explicitly listed in heading description. Serves as building block for nitrogen-sulfur chelators.
