TAMRA azide,6- isomer

Tetramethylrhodamine (TAMRA) is a xanthene dye with orange emission. The dye is a FRET acceptor for FAM, and sometimes used as a uencher for it.

Like other xanthenes, TAMRA exists as two isomers (5- and 6-), which have very similar spectral properties. This is an azide derivative of 6-isomer of TAMRA. The azide can be conjugated with terminal alkynes using copper-catalyzed Click chemistry, or with cycloalkynes with copper-free strain promoted alkyne azide cycloaddition (spAAc) reaction.
