TCI C1521 N-Carbobenzoxy-1,6-diaminohexane Hydrochloride (CAS 78618-06-1) is a mono-Cbz-protected hexamethylenediamine supplied as the hydrochloride salt. It completes the Cbz-diamine series with the longest spacer, offering a six-carbon chain that clearly separates two functional groups. The free amine couples readily with activated acids, NHS esters, isocyanates, and sulfonyl chlorides, after which hydrogenolysis unmasks the second amine for further elaboration. Available in 1 g and 5 g research packs; please refer to the TCI Certificate of Analysis and Safety Data Sheet for lot-specific technical and safety details.
