VIC is an asymmetric xanthene dye with spectral properties similar to HEX and JOE. Oligonucleotides labeled with VIC are often used in real-time PCR; the preparation of such oligonucleotides can be performed using click chemistry. This derivative is an azide, a pure 6-isomer, for conjugating VIC to other molecules by copper-catalyzed and copper-free click reactions.
