5(6)-Carboxyeosin diacetate is an amine-reactive, green-fluorescent probe that is commonly used as a photosensitizer and photooxidizer. It is non-fluorescent until the acetate groups are cleaved by either enzymes or by alkali hydrolysis. 5(6)-Carboxyeosin diacetate may be reactive with amines on biomolecules such as peptides, proteins, modified nucleotides and biopolymers using a carbodiimide like EDAC or DIPC to yield a robust amide linkage.

5(6)-Carboxyeosin diacetate is a useful phosphorescent probe or photosensitizer. Characterized by a high quantum yield for singlet oxygen generation, thereby making it an effective photooxidizer of diaminobenzidine (DAB). Suitable as fluorogenic substrate for esterases.
