Ur144 is my new subject study but need vender that can supply me with:
100grams of sodium hydroxide
200grams of TMCP-indol reagent
50grams of tetra-n-butylammonium bromide
200grams of amyl bromide.
Sodium hydroxide can be purchased at any hardware store. Or on the internet and totally legal as it is a toilet unblocker. For less than 10€, you can get 1kg.
