Z-Ala-Phe-Ser(OBzl)(OMe) is a tripeptide, a chain of three amino acids: Alanine (Ala), Phenylalanine (Phe), and Serine (Ser). The "Z" prefix indicates that the peptide is protected with a benzyloxycarbonyl (Cbz) group, which is a common strategy in peptide synthesis to prevent unwanted side reactions. The Serine residue has a benzyl (OBzl) protecting group on its hydroxyl group and a methoxyethyl (OMe) protecting group on its side chain. These protecting groups are crucial for the selective synthesis of complex peptides, as they prevent the amino acids from reacting at unwanted sites until the desired final product is achieved. The OBzl group can be removed under acidic conditions, while the OMe group can be cleaved under basic conditions, allowing for the controlled deprotection and assembly of the peptide chain. Z-Ala-Phe-Ser(OBzl)(OMe) is often used in the synthesis of larger peptides and proteins, where the precise sequence and protection of amino acids are essential for achieving the desired biological activity.

Check Digit Verification of cas no

The CAS Registry Mumber 98695-15-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,6,9 and 5 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 98695-15:
(7*9)+(6*8)+(5*6)+(4*9)+(3*5)+(2*1)+(1*5)=199
199 % 10 = 9
So 98695-15-9 is a valid CAS Registry Number.

Note on the Preparation of N-substituted Aminoglyceraldehydes

Angrick, Michael

, p. 645 - 650 (2007/10/02)

O-Benzyl-N-(benzyloxycarbonyl)-DL-serine methyl ester (1a) and peptides 1b-d with C-terminal O-benzylserine ester have been reduced with diisobutylaluminium hydride to yield the N-substituted aminoglyceraldehydes 2a-d.Using lithium tetrahydridoaluminate as the reducing agent the corresponding alcohols 3a-d have been obtained. - (Keywords: Maillard reaction; N-Substituted aminoglyceraldehydes)
