92943-93-6 Usage
Description
Gadolinium DOTA meglumine, also known as Gadoteric acid, is an organoammonium salt derived from the reaction of gadoteric acid with 1-deoxy-1-(methylamino)-D-glucitol (meglumine). It is a macrocyclic gadolinium-based contrast agent used in magnetic resonance imaging (MRI) to enhance the visualization of specific areas within the body.
Used in Medical Imaging Industry:
Gadolinium DOTA meglumine is used as a contrast agent for magnetic resonance imaging (MRI) in brain (intracranial), spine, and associated tissues of patients aged 2 years and older. It helps detect and visualize areas with disruption of the blood-brain barrier and/or abnormal vascularity of the central nervous system, improving the diagnostic accuracy of MRI scans.
Check Digit Verification of cas no
The CAS Registry Mumber 92943-93-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,9,4 and 3 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 92943-93:
(7*9)+(6*2)+(5*9)+(4*4)+(3*3)+(2*9)+(1*3)=166
166 % 10 = 6
So 92943-93-6 is a valid CAS Registry Number.

PROCEDURE FOR OBTAINING GADOTERATE MEGLUMINE FROM HIGH-PURITY TETRAXETAN (DOTA) AND ITS USE IN THE PREPARATION OF INJECTABLE GALENICAL FORMULATIONS
-
Page/Page column 10, (2021/12/31)
The present invention refers to a process for obtaining gadoterate meglumine from high purity tetraxetan (DOTA) which does not require the use of organic solvents and optimizes the conditions of the synthetic process. The tetraxetan from which the gadoterate meglumine is obtained by a synthetic process that includes a purification step in which at least one electrodialysis is performed. This procedure makes it possible to obtain a tetraxetan and a gadoterate meglumine with minimal amounts of impurities.
