General Description
Ethyl diatrizoate is a contrast agent used in medical imaging procedures such as X-rays, computed tomography (CT) scans, and angiography. It is a radiocontrast agent, meaning it helps to visualize and enhance the clarity of certain structures or organs within the body during these imaging procedures. Ethyl diatrizoate works by absorbing and reflecting X-rays differently than the surrounding tissues, allowing for greater contrast and visualization of the area being examined. It is commonly used to help diagnose and monitor conditions such as liver, gallbladder, and urinary tract disorders, as well as to aid in visualizing blood vessels and performing certain interventional procedures. Though generally safe and well-tolerated, there can be some side effects and risks associated with the use of ethyl diatrizoate, particularly for individuals with kidney or thyroid conditions. It is important for healthcare providers to carefully screen and monitor patients before and after using this contrast agent to mitigate potential adverse effects.
Check Digit Verification of cas no
The CAS Registry Mumber 2168-75-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,6 and 8 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2168-75:
(6*2)+(5*1)+(4*6)+(3*8)+(2*7)+(1*5)=84
84 % 10 = 4
So 2168-75-4 is a valid CAS Registry Number.

X-ray contrast compositions useful in medical imaging
-
, (2008/06/13)
An X-ray contrast composition comprising particles consisting essentially of a non-radioactive crystalline organic x-ray contrast agent having a surface modifier adsorbed on the surface thereof in an amount sufficient to maintain an effective average particle size of less than 400 nm, and a pharmaceutically acceptable carrier therefor is useful in x-ray diagnostic medical imaging methods. The agents can be delivered to a specific tissue or fluid site, for example, the blood pool, liver or spleen. In one embodiment involving intravenous administration, preferred compositions provide effective imaging of the blood pool for remarkably long times.
