Synthesis of hyperbranched polylysine using the N-hydroxysuccinimide ester of L-lysine dihydrochloride as AB 2 building block. The histidine and lysine standards were prepared from L-histidine monohydro- chloride and L-lysine dihydrochloride respectively. L-Homocitrulline-The copper complex was prepared from L-lysine dihydrochloride in 80 to 86 per cent yields.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
