H-CYS(ETHYLCARBAMOYL)-OH, also known as N-ethylcarbamoyl cysteine, is a chemical compound derived from the amino acid cysteine. It features a cysteine molecule with an ethylcarbamoyl group attached to its nitrogen atom. This modification of the cysteine structure can alter its chemical properties and reactivity, making it a useful compound in various applications, such as in the synthesis of pharmaceuticals or as a building block in peptide chemistry. The ethylcarbamoyl group introduces a new functional group that can participate in different types of chemical reactions, expanding the potential uses of the modified cysteine in research and industry.

4909-58-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4909-58-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,0 and 9 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4909-58:
(6*4)+(5*9)+(4*0)+(3*9)+(2*5)+(1*8)=114
114 % 10 = 4
So 4909-58-4 is a valid CAS Registry Number.

Cysteine thiol-protected peptides for use in immunoassays

-

, (2008/06/13)

Peptides immunoreactive with antibodies to native proteins, and which have at least two cysteine residues that contribute to mimicking an epitope of the protein, are prepared with the cysteine thiol groups protected. When deprotected, the peptides have enhanced immunoreactivity. The peptides are particularly useful for detecting antibodies or antigens associated with retroviruses, including the clinically important lymphotropic retroviruses HIV-1, HIV-2, HTLV-I, and HTLV-II
