BDP TR is a bright boron-dipyrromethene dye for ROX channels. It is an alternative to ROX and Texas Red. ROX and Texas Red dyes oxidize easily, BDP TR is more resistant to oxidizing agents. Its brightness and light stability are also very high. Such amine derivatives can be used in conjugation with electrophiles such as epoxides and activated carboxyl derivatives, as well as in enzymatic transamination reactions.
