Methyl-β-cyano-L-α-carbo benzoxyaminopropionate is a complex organic compound with the chemical formula C13H16N2O4. It is a derivative of amino acids, specifically a protected form of L-alanine, where the amino group is substituted with a benzyloxycarbonyl (Cbz) group, and the carboxylic acid group is replaced by a cyanomethyl group. methyl-β-cyano-L-α-carbo benzoxyaminopropionate is often used in peptide synthesis as a building block, where the Cbz group serves as a temporary protecting group for the amino group, preventing unwanted side reactions during the assembly of peptide chains. The cyanomethyl group is also a protecting group for the carboxylic acid, which can be removed under specific conditions to reveal the free carboxylic acid, allowing for further reactions or the formation of peptide bonds.

4909-53-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4909-53-9 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 3 respectively.
Calculate Digit Verification of CAS Registry Number 4909-53:
(6*4)+(5*9)+(4*0)+(3*9)+(2*5)+(1*3)=109
109 % 10 = 9
So 4909-53-9 is a valid CAS Registry Number.

Bis-morpholinophosphorylchloride, a novel reagent for the conversion of primary amides into nitriles

Rao, P. Purnachandra,Nowshuddin, Shaik,Jha, Anjali,Rao, B. Leela Maheswara,Divi, Murali K.,Rao

supporting information, (2021/01/21)

Bis-morpholinophosphorylchloride (Bmpc), in the presence of a base, is an efficient dehydrating agent for both aromatic and aliphatic primary amides, and gives corresponding nitriles under mild conditions in god yields and purity. During the reaction the enantiomeric integrity remains intact.
