GA20019
(2-{Ethyl-[4-(4-nitro-phenylazo)-phenyl]-amino}-ethoxy)-acetic acid-4-nitro-phenyl ester
Also known as (4-nitrophenyl) 2-[2-[N-ethyl-4-[(4-nitrophenyl)diazenyl]anilino]ethoxy]acetate
Incomplete coupling reactions during SPPS can be conveniently detected by treating a sample of the resin with NF31 (the p-nitrophenyl ester of the azo dye (2-{Ethyl-[4-(4-nitrophenylazo)phenyl]amino}ethoxy)acetic acid)· The NF31 assay is especially suitable for the detection of sterically hindered primary amines
