Description
TCI B6650, 4,4'-Methylenebis[N-(sec-butyl)aniline] (CAS 5285-60-9), is an aromatic diamine building block featuring two sterically hindered secondary amine groups linked by a diphenylmethane core. This hindered structure gives researchers a more controlled reactivity profile compared with simple primary aromatic amines, which is useful in stepwise coupling and curing studies. It is widely applied in organic synthesis as well as in polyurea, polyurethane, and epoxy formulation research. AMI Scientific supplies this TCI product in 100 g and 500 g pack sizes to suit both exploratory and routine laboratory work.
