What is 2-Aminoperimidine Hydrobromide?
What are the applications of Application
Formation of an ion associated with the excess of 2-aminoperimidine hydrobromide (Ap) and sulfate ion in the sample solution and detection of the concentration of the remaining Ap ion by the optode. The developed optode method could be applied to determine sulfate ions in environmental water samples[1].
Purification Methods
Purify the hydrobromide by boiling a saturated aqueous solution with charcoal, filtering and leaving the salt to crystallise. Store this dihydrate salt in a cool, stoppered flask in the dark place. The anhydrous salt is obtained by heating at 80o/4hours, and it is hygroscopic. The solubilities of the hydrobromide at 26o are 2.4% in EtOH, 0.6% in H2O, 0.3% in Et2O, 0.1% in Me2CO and 0.003% in *C6H6. [Dasgupta et al.
