SWIM's two lots of M1, same supplier..
First lot hit with marquis,
Second lot hit with marquis,
This lots contained 3 crystal forms,
Large transparent crystal (left)
Large yellow crystal (right)
Small uniform crystal resembling previous M1. (produced same reaction as Large transparent not the same as previous M1)
Supplier assures they're the same compound...
Further testing with other reagents to continue when they arrive...
Any thoughts on these worrisome results?
