Common Name(2s,3s,6r,8r)-4-chloro-3-ethenyl-2-isothiocyanato-3,7,7,10-tetramethyl-10-azatetracyclo[6.6.1.1²,⁶.0¹¹,¹⁵]hexadeca-1(14),4,11(15),12-tetraene-9,16-dione
DescriptionN-Methylwelwitindolinone C isothiocyanate, also known as N-me-wc-NCS, belongs to the class of organic compounds known as indoles and derivatives. These are organic compounds containing an indole, which is a bicyclic ring system made up of a six-membered benzene ring fused to a five-membered nitrogen-containing pyrrole ring.
