CAS :Calcobutrol is a calcium salt that is the byproduct of the reaction between phosphoric acid and calcium carbonate. It has been crystallised as an acidic calcium phosphate salt. Calcobutrol has a molecular weight of 210.13 g/mol and a melting point of 240°C. The compound is insoluble in water, but can be dissolved in dilute acids or alkalis. Calcobutrol has shown to have a ligand affinity for gadolinium (Gd3+), which may be due to its ability to bind with phosphate ions and sodium ions.
Calcobutrol diffracts X-rays with a wavelength of 0.154 nm, which corresponds to its crystal lattice spacing of 0.154 nm, and has been used as a standard for this type of diffraction in studies on Gd3+.Formule :C36H62Ca3N8O18Degré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :1,015.15 g/mol
