    Price insanity for 2-bromo-3-methylpropiophenone compared to 2b4m + some quotes to compare

    Could be wrong, but If it was that easy, nobody would pay ~2500usd/kg 2b3m. They would just turn 3chloro to 3methyl easily and brominate to 2b3m themselves.

    something is buggy here, copy of the concerning message ---------------------- Unfortunately, this product (2-bromo-3-methylpropiophenone-1451-83-8 ) is controlled by government and there is no manufacturer can offer it. So it is not available at the moment. ---------------------------

    Is there anyone with knowledge whether the liquid form can be used in the same manner as the powdered version? eg : dissolving => amination => acidification. i wouldn't see a reason why not, but thats, well.. me.

    Maybe the answer of the high price is the following message I received from a manufacturer which concerns me.

    That may be, but not in Europe. You could give away 4mmc for free and they won't even bother picking it up (so to speak). For 3mmc that's a completely different story

    Have some patience 😋 Regarding the 3cmc and other stuff being sold as 3mmc. If they only had some ethics left in their balls then at least sell 4mmc as 3mmc.

    Thanks for your responses. It makes sense, although i'm not sure if the chinese are really bookkeeping what countries put what substances on what schedules. I will make some orders and test it out.

    TheVacuumGuy's guide to building a multipurpose vacuum pump.

    I did mention ice for real power. I built mine 14 months ago and I've used ice 2 times (for testing). Why would I need to go sub millibar ? With metal ones, try pumping some acid through it and see what happens. And glass one is not for me. I'm the guy needing to weekly order some glassware...

    4′-Methylpropiophenone bromination to 2-bromo-4'-methylpropiophenone. Large scale.

    Second attempt after the first one which yielded granules. 💯 Best recipe . Just do it in a cold water bath against overheating.

    I can walk into almost any store and get methylamine 😋 But a hole in your knee in 10 seconds is maybe what you *thought* have happened. Unless it spoiled in your face or somewhere between the legs, you can finish what youre doing and do the rinsing a minute later. If it were nitric acid, make...
