The succinimidyl ester of the fluorescent molecular rotor CCVJ (Cat. No. 227025). This amine-reactive molecule is useful for labeling proteins, antibodies, and small molecules. CCVJ is characterized by a charge-transfer excited singlet state that can rapidly deactivate through internal rotation about the donor-acceptor bond. Intramolecular rotational relaxation is solvent-dependent. Its quantum yield increases with decreasing free volume, hence it is very useful in monitoring synthetic polymer reactions and measuring local microviscosity changes in phospholipid bilayers. In a highly constrained environment such as in a high viscosity solvent, the predominant decay path is radiative resulting in a large increase in the fluorescence quantum yield. Absorbs strongly in the blue region (~450 nm).
