Plavix (clopidogrel bisulfate) is an inhibitor of P2Y12 ADP platelet receptors. Plavix is used to prevent heart attacks and strokes in persons with heart disease. You have dropped a 2.5 kilogram sample of crystalline Plavix (mp = 198-200 degree C) on the ground where it has been mixed with sand, charcoal, dust, and broken glass. What would be the ideal solvent to use to start a recrystallization of the Plavix sample? a) A solvent that rapidly dissolves Plavix at low temperature b) A solvent that reacts with Plavix at high temperature c) A solvent that dissolves Plavix at high temperature d) A solvent that does not dissolve Plavix at any temperature With problem 1 answered, the most effective way to remove the insoluble impurities from the Plavix solution would involve which technique? a) vacuum filtration b) cold filtering c) gravity filtration d) inverse low temperature filtration Once crystals have formed, what would be best the way to collect the crystals? a) vacuum filtration b) cold filtering c) gravity filtration d) inverse low temperature filtration
