hey guys,
got mxe in the mail from the vendor turcs on evo a few days ago. great shipping speed and ok stealth. but anyways, i got around to testing the mxe with the mandelin reagent yesterday, and I'm a little concerned with the results.
everywhere I've searched (including the bunk police sheet) says that mxe should go from yellow/green quickly, then to brown over time at the end of the reaction. i had high hopes when turcs mxe initially turned yellowish green, however, a few minutes into the reaction, the green liquid gave way to a light blue color. and over time, it became apparent that this reaction wasn't going to go to brown, like mxe should. it ended clearly pale blue, with some green/yellowish stuff. pics here: http://imgur.com/a/8glS1. the pictures are spaced out about 10-20 seconds from each other.
I was wondering if anyone has any ideas as to what might cause this reaction to go to blue rather than brown. my guess is either impure/cut product, despite turcs good reviews. when i asked turcs about this issue, he claimed that each polymorph of mxe tests differently. I'm no scientist, but this sounds like bs to me...what do you guys think? I just want to make sure this is safe to use, don't wanna spread any FUD if theres nothing to worry about!
I also have the marquis and mecke reagents as well, if that will help further identify the substance or if you have any advice/experience with testing mxe, please let me know.
I'm no chemist, but starting to believe this could be quite true. Had similar results with different batches before, including different lots of RCS14 etc. Our guess is that various polymorphs may mess with final color, but as long as we're getting a yellow/green at the start, there doesn't seem to be much issue. Haven't noticed it impacting on strength, quality etc either. So while it sounds like a bit of a crapshoot, it is appearing the initial colors are the one to watch, as we've no idea what the final colors mean, and can't find it correlating to anything either.
Don't take any of that as a carte blanche 'it's fine', but there may be less cause for concern than what it first looks.
