ATT 633 is a far-red fluorescent dye with high fluorescence quantum yield, strong thermal and photostability, and excellent water solubility. The dye is well-suited for high-resolution microscopy and single-molecule detection applications.

ATT 633 is a cationic dye. After coupling to a substrate, the dye carries a net electrical charge of +1.

ATT 633 azide is a fluorescently labeled azide that reacts with alkynyl derivatives of biomolecules (terminal alkynes and cyclooctynes) via click reactions to form stable adducts.
