从China供应商批量进口4-Dodecylaniline

4-Dodecylaniline is an alkyl-substituted aniline used as a key intermediate in the synthesis of surface-reactive dyes for textile applications. The compound features a dodecyl chain attached to the 4-position of the aniline ring, delivering solubility in non-polar solvents and compatibility with hydrocarbon-based substrates. It is supplied as a pale to light amber liquid or low-melting solid, depending on ambient temperature, and maintains thermal stability up to 200 °C under inert conditions.

In dye manufacture, 4-Dodecylaniline contributes to the formation of azo and anthraquinone chromophores, which yield vibrant, wash-fast colors on natural and synthetic fibers. Typical industry grades for this intermediate target a minimum assay of 98 % by GC, with iron content held below 10 ppm and water content below 0.5 % to prevent catalytic side reactions. The alkyl tail improves diffusion into polymer matrices, making it valuable for spin-dyeing polyester and polyamide.

Textile mills and specialty chemical manufacturers in Asia and Europe source this material for high-performance dye batches. Buyers confirm packaging in 25 kg or 200 L steel drums with nitrogen padding to inhibit oxidation. Trade terms commonly negotiated include CIF main port China and L/C at sight, with lead times tied to vessel schedules from Tianjin or Shanghai. Each lot is accompanied by a certificate of analysis listing GC purity, moisture, and heavy metal content.

Anyang Qianhe Dyestuff Chemical Co.,Ltd. operates from Dongzhangjian in Henan Province, China, where it focuses on the production of dye intermediates and specialty chemicals. The firm is classified as an imported-tier supplier with a harbor trust tier, indicating a baseline verification level for international trade.
