Description

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution, 42373-04-6 C.I. Basic Red 29 3-Methyl-2-((1-methyl-2-phenyl-1H-indol-3-yl)azo)thiazolium chloride Thiazolium, 3-methyl-2-((1-methyl-2-phenyl-1H-indol-3-yl)azo)-, chloride Thiazolium, 3-methyl-2-(2-(1-methyl-2-phenyl-1H-indol-3-yl)diazenyl)-, chloride (1:1) Basacryl Red GL Basic Red 29 CCRIS 894 EINECS 255-785-4 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 386.02 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
