Are you familiar with testing for MgBr2 in a commercially available allyl magnesium bromide solution?

Thanks in advance for your replies.

If you have access to a good NMR spectrometer (500 MHz or better), you can easily distinguish Mg++ from a Grignard reagent by 25Mg NMR. I believe the peaks can be integrated to give relative concentrations; if not you can add measured amounts of MgBr2 and obtain a calibration curve.
