Description: Flow cytometry measurement tool. Fluorescence probe for glutathione and glutathione disulfide levels, primary amines, peptides and biological thiols. Reacts with primary amines to produce a product that emits a highly fluorescent blue colour. Spectral data: ?ex 334 nm, ?em 455 nm (Thiol Adduct). Used for the quick visualization of histamine, characterized by the appearance of a yellow stain. Used for precolumn derivatization of amino acids for HPLC separation. High-level disinfectant/sterilant for endoscopes, thermometers, rubber and plastic equipment, and medical/surgical instruments that cannot be sterilized by heat, based on its antimicrobial efficacy and low inhalation toxicity.
Smiles: [H]C(C1=C(C([H])=O)C=CC=C1)=O
