Brief Introduction
Once widely used in cotton; For the dyeing of viscose, it is easy to change into blue in case of acid, and there is no appropriate treatment method to improve its wet treatment fastness. Therefore, since the advent of insoluble azo dye and direct acid resistant red 4BS, the use of this product in dyeing has decreased gradually, but it is used in papermaking industry. It can also be used as acid-base indicator, i.e. Congo red test paper, pH 0 (blue violet) - 0 (red). In addition, it is also used for biological staining and analytical reagents. It is used as an adsorption indicator for the determination of halide, thiocyanate and zinc. It is used as a chromogenic agent for the determination of thiophosphate herbicides by TLC. It is also used as a biological stain.
