Z-Tyr-Pro-OBut is a peptide compound consisting of three amino acids: Tyrosine (Tyr), Proline (Pro), and a protected form of Alanine, specifically tert-butyloxycarbonyl (Boc) protected Alanine (OBut). The "Z" prefix indicates that the peptide is protected with a benzyloxycarbonyl group, which is a common protecting group used in peptide synthesis to prevent unwanted side reactions. Z-Tyr-Pro-OBut is often used in the synthesis of larger peptides and proteins, where the protecting groups are removed at specific stages to allow for further reactions. The OBut group on the Alanine residue is a temporary protective group that shields the carboxyl group, ensuring that the peptide chain grows in a controlled manner during synthesis.

Check Digit Verification of cas no

The CAS Registry Mumber 84552-62-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,5,5 and 2 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 84552-62:
(7*8)+(6*4)+(5*5)+(4*5)+(3*2)+(2*6)+(1*2)=145
145 % 10 = 5
So 84552-62-5 is a valid CAS Registry Number.

4-Methoxy-2,3,6-trimethylbenzenesulfonyl (Mtr): a New Amino and Imidazole Protecting Group in Peptide Synthesis

Wakimasu, Mitsuhiro,Kitada, Chieko,Fujino, Masahiko

, p. 2766 - 2779 (2007/10/02)

The 4-methoxy-2,3,6-trimethylbenzenesulfonyl (Mtr) group was introduced as a protecting group for the amino function, especially the ε-amino function of lysine, and the imidazole ring of histidine.The Nε-Mtr group was removable by dilute methanesulfonic acid-containing trifluoroacetic acid-thioanisole, but was stable to trifluoroacetic acid or catalytic hydrogenation.The Nim-Mtr group was removable by trifluoroacetic acid-dimethylsulfide or 1-hydroxybenzotriazole, but was more stable than the Nim-Tos or the Nim-Mbs group with triethylamine.To examine the usefulness of the Mtr group as a protecting group for use in peptide synthesis, mastoparan X and chicken gastrin releasing peptide (c-GRP) were synthesized, and this group was found to be very convenient for general solution synthesis.In particular, the introduction of Lys(Mtr) made possible a new strategy in peptide synthesis.Keywords-4-methoxy-2,3,6-trimethylbenzenesulfonyl (Mtr); Nε-4-methoxy-2,3,6-trimethylbenzenesulfonyllysine; Nim-4-methoxy-2,3,6-trimethylbenzenesulfonylhistidine; methanesulfonic acid-trifluoroacetic acid-thioanisole deprotection; trifluoroacetic acid-dimethylsulfide deprotection; mastoparan X; chicken gastrin releasing peptide
