Dansyl-L-methionine cyclohexylammonium salt (CAS 53332-30-2)

Dansyl-L-methionine cyclohexylammonium salt is a chemically modified amino acid, where L-methionine is tagged with a dansyl group (a dimethylaminonaphthalenesulfonyl group), and is paired with a cyclohexylammonium counterion to form a salt. The dansyl group is a fluorescent probe used in biochemistry and analytical chemistry for labeling proteins, peptides, and other biomolecules, facilitating their detection and study under fluorescent microscopy or spectroscopy. This fluorescence tagging allows for the detailed study of metabolic pathways, protein synthesis, and the role of methionine in various biological processes, including methylation reactions and antioxidant defense mechanisms. The presence of the cyclohexylammonium salt improves the solubility of the compound in aqueous solutions, making it more accessible for biological reactions and easier to handle in experimental setups. This property is particularly beneficial in studies involving cell cultures or enzymatic reactions, where water solubility is for the bioavailability of the reagent.
