I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 153-94-6, help many people in the next few years.Quality Control of: H-D-Trp-OH
Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels.In a patent， Quality Control of: H-D-Trp-OH, Which mentioned a new discovery about 153-94-6
The syntheses are described of cyclo-<somatostatin-(5-12)-peptide> (77), and (79)-(82) labelled singly at positions 6, 7, 8, and 11 and doubly at residues 6 and 11 to specific radioactivities of between 4.8 and 22.4 Ci mmol-1.The linear sequence (5-12) and the related cyclo<somatostatin-(5-12)-peptide> (78) and (83) were also prepared to specific radioactivities of 19.2 and 19.6 Ci mmol-1 respectively.The syntheses of the labelled hexapeptide cyclo-<<4-(3)H-Phe7,D-Trp8,Pro12>somatostatin-(7-12)-peptide> (84) and full sequences <4-(3)H-Phe6,D-Trp8,D-Cys14>somatostatin (94) and somatostatin (95) labelled at ca. 13.0 Ci mmol-1 are described.Labelling was effected by reductive dehalogenation in the presence of tritium of the fully protected precursors and the purity of the final products was assessed by amino acid analysis after acidic hydrolysis following purification by ion-exchange and h.p.l.c. as appropriate.
