Seeking help regarding what kind of product “carbazole” is
Thread Content
I came across this product by chance recently; it’s used as a pigment. A few years ago, when it was in demand, its price reached over 50,000. Currently, the price is around 20,000 or so. I’m wondering if anyone who has experience in this field knows anything about this product. I’d like to know whether there are any synthetic methods apart from separating it from crude anthracene Also, with such large price fluctuations these days, could it be that these products are already in surplus? What are some well-known manufacturers in China? Everyone is welcome to share relevant information; thank you!
Carbazole is mainly used as a raw material for Permanent Violet; due to anti-dumping measures in the United States last year, its price soared
