Import Tips & Compliance

Specify salt counterion in COA; hydrochloride typical but others qualify if protonated

Declare pH stability data; salts more stable than free base for import handling

Segregate from oxidizers in shipping; thiols highly reactive even in salt form

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.
