721-65-3 Usage
General Description
N-Chloroacetyl-L-phenylalanine is a chemical compound that combines the amino acid phenylalanine with a chloroacetyl group. It is commonly used in the synthesis of peptides and proteins by introducing the N-chloroacetyl group to the amino acid side chains. This chemical plays a crucial role in the preparation of peptide-based drugs and pharmaceuticals due to its ability to facilitate peptide bond formation and modification. Additionally, N-Chloroacetyl-L-phenylalanine can also be used as a precursor in the development of various bioactive compounds and in the study of protein structure and function. It is important to handle this compound with care as it may pose health hazards and should only be used in a controlled laboratory setting.
Check Digit Verification of cas no
The CAS Registry Mumber 721-65-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,2 and 1 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 721-65:
(5*7)+(4*2)+(3*1)+(2*6)+(1*5)=63
63 % 10 = 3
So 721-65-3 is a valid CAS Registry Number.

A convenient one-pot synthesis of phenylseleno N-acetyl α-amino acids, PhSeCH2C(O)NHC(R)COOH (R = H (1), Me (2), PhCH2 (3), 4-HOC6H4CH2 (4) and CH2OH (5)) is reported. These compounds have been characterized by microanalyses, UV-Vis, IR and NMR (1H, 13C, 77Se) spectroscopy. The molecular structures of [PhSeCH2CONHCH2COOH] (1), [PhSeCH2CONHCH(CH2C6H4OH-4)COOH] (4) and [PhSeCH2CONHCH(CH2OH)COOH] (5) have been established by X-ray diffraction analyses. These compounds are associated in the solid state through hydrogen bonding to give supra-molecular self-assembled structures. Free radical scavenging activity of these compounds has also been evaluated by DPPH assay.
