IR 750 DBCO is a fluroescent molecule with a terminal DBCO group. IR 750 DBCO is a near-red, water-soluble dye that is structurally similar to other 750 dyes which absorbs at 756 nm and emits at 776 nm. The DBCO groups is commonly used for copper-free Click Chemistry reactions due to its strain promoted high energy. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
