Product Description Chemical name: N6-Trifluoroacetyl-L-lysine N-Carboxyanhydride, N6-Trifluoroacetyl-L-lysine NCA Synonyms: N-[4-[(4S)-2,5-Dioxo-4-oxazolidinyl]butyl]-2,2,2-trifluoroacetamide; (S)-N-[4-(2,5-Dioxo-4-oxazolidinyl)butyl]-2,2,2-trifluoroacetamide; Lys(Tfa)-NCA; CAS Number: 42267-27-6 Possible CAS #: NA Molecular form.: C₉H₁₁F₃N₂O₄ Appearance: White to Off-White Solid Melting Point: 98-101°C Mol. Weight: 268.19 Storage: -20˚C Freezer, Under Inert Atmosphere Solubility: DMSO, Ethyl Acetate Stability: No Data Available Category: Amino Acids & Derivatives, Aromatics, Chiral Reagents, Heterocycles, Boiling Point: No Data Available Applications: Used in the synthesis of new arborescent architectures of poly(L-lysine), called lysine dendrigraft (DGL) polymers.  DGL polymers were prepd. through a multiple-generation scheme (up to generation 5) in a weakly acidic aq. medium by polycondensing N.vepsiln.-trifluoroacetyl-L-lysine-N-carboxyanhydride (Lys(Tfa)-NCA) onto the previous generation G(n-1) of DGL, which was used as a macroinitiator.
