Derivatization Reaction

Product Description
DDB reacts with aromatic aldehydes in acidic conditions to give strong fluorescent benzimidazole. This reagent, as well as DTAN, can be used for the detection of aromatic aldehydes. DDB is soluble in aqueous solutions. The excitation and emission wavelength of the labeled materials are 338 nm and 402 nm, respectively.
