MB 660R Azide is a fluorescent probe with a terminal azide group. The MB 660R fluorescent molecule is a water-soluble, pH-insensitive from pH 4 to pH 10, far-red and near-IR fluorescent probe that maximally excitates at 633 nm and emits at 690 nm. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage and as an azide-copper complex. The reaction works well under diluted conditions.
