Hydrochloric Acid → Ethanol DMPE

Participants

Reaction Steps

Prepare a saturated solution of sodium chloride in ethanol by dissolving 117 mg of sodium chloride in 20 ml of degassed ethanol. Add 11.1 μl of liquid DMPE to this solution and adjust its pH to approximately 2.25 by adding concentrated hydrochloric acid. Dispense 5 ml into a 10 cc vial and crimp seal it using a teflon-coated stopper. Inject approximately 5 mCi of 99mTc-pertechnetate eluate into the vial and place it in a boiling water bath for 1 hour. HPLC analysis shows a yield of greater than 80% of the [99mTcCl2 (DMPE)2 ]+ complex.
