L-Valine, N-[N-[N-[(phenylmethoxy)carbonyl]-L-leucyl]-L-phenylalanyl]-, 1,1-dimethylethyl ester is a complex organic compound with the chemical formula C31H41N3O5. It is a derivative of L-valine, an essential amino acid, and is characterized by the presence of a phenylmethoxycarbonyl group attached to the leucine residue, which is further connected to a phenylalanine residue. The compound also features a 1,1-dimethylethyl (tert-butyl) ester group, which is a bulky, non-polar group that can influence the compound's solubility and reactivity. This specific arrangement of amino acids and functional groups is not found in naturally occurring proteins, making it a synthetic peptide with potential applications in pharmaceuticals, as a research tool, or in the development of novel bioactive molecules.

2073-67-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2073-67-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,7 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2073-67:
(6*2)+(5*0)+(4*7)+(3*3)+(2*6)+(1*7)=68
68 % 10 = 8
So 2073-67-8 is a valid CAS Registry Number.

STUDIES ON AMINO ACIDS AND PEPTIDES X. HPLC-MEDIATED TEST OF 2,4-BIS(4-METHOXYPHENYL)-1,3,2,4-DITHIADIPHOSPHETANE 2,4-DISULFIDE (LAWESSONS'S REAGENT) AS A RACEMIZATIONFREE COUPLING REAGENT IN PEPTIDE SYNTHESIS

Thorsen, M.,Andersen, T. P.,Pedersen, U.,Yde, B.,Lawesson, S.-O.,Hansen. H. F.

, p. 5633 - 5636 (2007/10/02)

The easily available 2,4-bis(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane 2,4-disulfide (Lawesson's Reagent), 1, has been tested as a coupling reagent for racemization in peptide synthesis.The assay procedure is separation of stereomeric products by HPLC.Z-S-Pro-S-Val-S-Pro-OtBu and Z-S-Leu-S-Phe-S-Val-OtBu have been used as test peptides in 2+1 segment couplings, and only a small amount of epimerization (0.5 and 0.1percent, respectively) has been observed.
