56104-22-4 Usage
General Description
PYR-GLN-PHE-PHE-GLY-LEU-MET-NH2 is a peptide composed of seven amino acids. It starts with the amino acid pyrrolidine (PYR) and ends with a carboxamide group (NH2), which determines its linear structure. The amino acid sequence includes glutamine (GLN), phenylalanine (PHE) repeated twice, glycine (GLY), leucine (LEU), and methionine (MET). This peptide is commonly used in research and drug development due to its potential bioactivity and pharmacological properties. It may have various biological functions, such as neurotransmitter modulation, antimicrobial activity, or as a substrate for enzymatic reactions. Its precise role and application depend on the specific context and intended use in scientific investigations or medical interventions.
Check Digit Verification of cas no
The CAS Registry Mumber 56104-22-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,1,0 and 4 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 56104-22:
(7*5)+(6*6)+(5*1)+(4*0)+(3*4)+(2*2)+(1*2)=94
94 % 10 = 4
So 56104-22-4 is a valid CAS Registry Number.

Catalytic Transfer Hydrogenation in Synthesis of Substance P
Sivanandaiah, K. M.,Rangaraju, N. S.
, p. 787 - 792 (2007/10/02)
The utility of catalytic transfer hydrogenation (CTH) in the synthesis of longer peptides has been demonstrated by the stepwise synthesis of Substance P in the solution phase.The technique of CTH using formic acid as a hydrogen donor provides a facile method for the removal of protecting groups such as benzyloxycarbonyl and nitro in the synthesis of medium-sized peptides also.Except in the case of glutaminyl peptides where the purity and yield are affected to some extent by cyclization, the products are generally pure requiring minimum purification and the yields are good.
