Dye Intermediates (for Research and Experimental Use) — compiles aromatic intermediate compounds, namely derivatives of aniline, phenol, and nitroaniline bearing amino, chloro, or nitro groups, which serve as the main building blocks in the synthesis of azo dyes and other aromatic colorants. This substituted benzene ring structure enables diazotization, coupling, and electrophilic substitution reactions, which are the key steps in forming the chromophore.
Dye Intermediates are used by organic chemistry researchers and textile dye developers to design synthetic routes for azo dyes through diazotization and aromatic coupling reactions, and as precursors for pigments and laboratory indicators. Chloroaniline and nitroaniline derivatives also serve as intermediates in the development of photographic compounds and in further synthetic chemistry research.
Examples of products in this collection: TCI A0106 122-80-5 4'-Aminoacetanilide, TCI C0113 141-85-5 3-Chloroaniline Hydrochloride, TCI A0284 95-85-2 2-Amino-4-chlorophenol, TCI C0114 137-04-2 2-Chloroaniline Hydrochloride, TCI A0335 95-55-6 2-Aminophenol, TCI C0215 89-63-4 4-Chloro-2-nitroaniline, TCI A0379 119-34-6 4-Amino-2-nitrophenol, TCI C0746 6259-42-3 5-Chloro-2-methylaniline Hydrochloride.
Pay attention to purity and form of the compound (free base or hydrochloride salt), since the positional isomers of the substituents (ortho, meta, para) strongly affect the coupling reaction pathway and the color of the final product. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
