butaxamine butaxamine butaxamine (inn, also known as butoxamine) is a β2-selective beta blocker. its primary use is in experimental situations in which blockade of β2 receptors is necessary to determine the activity of the drug (i.e. if the β2 receptor is completely blocked, but the given effect is still present, the given effect is not a characteristic of the β2 receptor). it has no clinical use. an alternative name is α-(1-ethyl)-2,5-dimethoxybenzyl alcohol. butaxamineclinical dataatc codenoneidentifiers iupac name (1s,2s)-1-(2,5-dimethoxyphenyl)-2-(tert-butylamino)propan-1-ol cas number2922-20-5 ypubchem cid21909chemspider20593 yunii0nm31m53pwchemblchembl289093chemical and physical dataformulac15h25no3molar mass267.369 g·mol−13d model (jsmol)interactive image smiles cl.o(c1ccc(oc)cc1c(o)c(nc(c)(c)c)c)c inchi inchi=1s/c15h25no3.clh/c1-10(16-15(2,3)4)14(17)12-9-11(18-5)7-8-13(12)19-6;/h7-10,14,16-17h,1-6h3;1h ykey:urpaecskkqlcii-uhfffaoysa-n y (verify)
