17879-97-9 Usage
Uses
Used in Medical Imaging:
(-)-Iopanoic acid is used as a radiographic contrast agent for enhancing the visualization of the bile ducts and gallbladder during cholecystography. It allows for improved radiographic imaging and diagnosis of various conditions such as gallstones, tumors, and other abnormalities.
Used in Diagnostic Procedures:
(-)-Iopanoic acid is used as a diagnostic aid for identifying and assessing abnormalities in the gastrointestinal system. Its administration, either orally or through direct injection, is typically accompanied by monitoring for potential adverse reactions such as allergic responses, and thyroid and kidney dysfunction.
Check Digit Verification of cas no
The CAS Registry Mumber 17879-97-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,8,7 and 9 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 17879-97:
(7*1)+(6*7)+(5*8)+(4*7)+(3*9)+(2*9)+(1*7)=169
169 % 10 = 9
So 17879-97-9 is a valid CAS Registry Number.

CHEMOENZYMATIC SYNTHESIS OF THE ENANTIOMERS OF IOPANOIC ACID

The two enantiomers of Iopanoic acid 1 were prepared in enantiomeric excess higher than 90percent by enzyme-catalyzed hydrolysis of precursors (+/-)-2a and (+/-)-3a, followed by standard chemical transformations.Among the tested enzymes, chymotrypsin and Lipase PS proved to be the most selective catalysts.The stereochemical outcome of the lipase-catalyzed hydrolyses of esters (+/-)-2a-d is strictly dependent upon both the size of the alkyl group attached to the chiral center and the substituent in the aromatic ring.The enantioselectivity of the reactions was evaluated by chiral HPLC and the configurations of the new products were assigned by chemical correlations.
