(R)-2-(4-((2-Hydroxy-3-(4-(trifluoromethyl)phenoxy)propyl)thio)-2-methylphenoxy)acetic acid,L-lysine

(R)-2-(4-((2-Hydroxy-3-(4-(trifluoromethyl)phenoxy)propyl)thio)-2-methylphenoxy)acetic acid, L-lysine is a salt formed between a complex phenoxyacetic acid derivative and the amino acid L-lysine. The molecule contains aromatic rings, a trifluoromethyl group, ether and thioether linkages, and a hydroxyl group. Converting it into the L-lysine salt form typically improves its water solubility and stability, which is useful in pharmaceutical development.
