MeCN?Yes, beat me now, spank me nice and hard
About the industrial scale thing... I'm aware of that, but the problem is that I can't just order solvents in enormous bulk quantities. Even don't have enough place to store them safely. When I was still at high school, the chem lab organizer ordered filters and other simple utilities at a company specialized in Biology laboratory materials. Price was 70% less. Only reason is the typical one: 'chemical industry'. You can see the same for pharmaceutical supplies... outrageous profit margins. Or specialized fields like GC supplies. I installed a new multiplier three weeks ago. It's half the size of my pink and costs US$ 1200...
And about Aldrich: yes, they stink
. I once ordered alpha-pinene from them, which was supposed to be 99+% pure. God bless GCs.... purity even wasn't 80%. Same for Merck's benzaldehydes. Some lots seem to be OK, others need some purification. Also, I don't understand why some catalogues seel a product at 5$/10 gram and at 10$/500 gram...
