Butanoic acid, 2-[[(phenylmethoxy)carbonyl]amino]-, 4-nitrophenyl ester, (R)- is a complex organic compound with the chemical formula C18H18N2O6. It is a chiral molecule, meaning it has a non-superimposable mirror image, and in this case, it is the (R)-enantiomer. Butanoic acid, 2-[[(phenylmethoxy)carbonyl]amino]-, 4-nitrophenyl ester,
(R)- is characterized by a butanoic acid backbone, which is a four-carbon chain with a carboxylic acid group at one end. The 2-position of the butanoic acid is substituted with an amino group that is further modified by a phenylmethoxycarbonyl group, which is an ester derived from phenylmethanol and carbonic acid. The 4-nitrophenyl ester group is attached to the carboxylic acid, providing a nitro group-substituted phenyl ring. Butanoic acid, 2-[[(phenylmethoxy)carbonyl]amino]-, 4-nitrophenyl ester,
(R)- is significant in the field of organic chemistry, particularly in the synthesis of pharmaceuticals and as a potential intermediate in the preparation of various biologically active molecules.
The CAS Registry Mumber 2900-21-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,0 and 0 respectively; the second part has 2 digits, 2 and 1 respectively. Calculate Digit Verification of CAS Registry Number 2900-21: (6*2)+(5*9)+(4*0)+(3*0)+(2*2)+(1*1)=62 62 % 10 = 2 So 2900-21-2 is a valid CAS Registry Number.
