Doing a google search I found in the vitamin section a vitamin called DMG.
It is listed as Dimethylglyocine vs dimethylglyoxime.
I am by no means a chemist but what is the difference between glyocine and glyoxime?
You want dimethylglyoxime for refining purposes,just because they call the other DMG doesn't make it work for palladium or nickel testing.
Dimethylglyoxime is kind of hard to find and expensive,but if you need it, you need it.
