737-31-5 Usage
Description
Diatrizoate sodium is a contrast agent used during the X-rays test. It can be used as a diagnostic aid agent during angiography, urography and radiography. It can be applied during visualizing veins, the urinary system, gastrointestinal tract, spleen and joints as well as during the computer tomography (CT scan). It is used in cases where barium is not suitable for application such as patient being allergic to barium. The mechanism of action of Diatrizoate sodium is that it can block the X-rays so that the body structure containing iodine to be delineated in contrast to those structures that free of iodine, further allowing the visualization of those related areas.

Definition
ChEBI: The sodium salt of a benzoic acid having iodo substituents at the 2-, 4- and 6-positions and acetamido substituents at the 3- and 5-positions. It is used, often as a mixture with the meglumine salt, as an X-ray contrast medium in gastrointestinal studies,
ngiography, and urography.

Check Digit Verification of cas no
The CAS Registry Mumber 737-31-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,3 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 737-31:
(5*7)+(4*3)+(3*7)+(2*3)+(1*1)=75
75 % 10 = 5
So 737-31-5 is a valid CAS Registry Number.

Insights into the crystallisation process from anhydrous, hydrated and solvated crystal forms of diatrizoic acid

Diatrizoic acid (DTA), a clinically used X-ray contrast agent, crystallises in two hydrated, three anhydrous and nine solvated solid forms, all of which have been characterised by X-ray crystallography. Single-crystal neutron structures of DTA dihydrate and monosodium DTA tetrahydrate have been determined. All of the solid-state structures have been analysed using partial atomic charges and hardness algorithm (PACHA) calculations. Even though in general all DTA crystal forms reveal similar intermolecular interactions, the overall crystal packing differs considerably from form to form. The water of the dihydrate is encapsulated between a pair of host molecules, which calculations reveal to be an extraordinarily stable motif. DTA presents functionalities that enable hydrogen and halogen bonding, and whilst an extended hydrogen-bonding network is realised in all crystal forms, halogen bonding is not present in the hydrated crystal forms. This is due to the formation of a hydrogen-bonding network based on individual enclosed water squares, which is not amenable to the concomitant formation of halogen bonds. The main interaction in the solvates involves the carboxylic acid, which corroborates the hypothesis that this strong interaction is the last one to be broken during the crystal desolvation and nucleation process.
