Strong quality control system: Strength of our ethical commitment to quality control and quality assurance systems firmly based on ISO standard. QA and QC used in the whole process of raw material control, process control and finished product quality inspection.

Physicochemical properties:

It is slightly soluble in ethanol, which creates a certain stimulating effect to skin and respiratory tract.The product is not in the list of toxic and hazardous chemicals, but it possesses a little toxicity from aniline and nitro organics, so it shall seek medical advice for eating by mistake. It is combustible material. In acid solution, the sodium salt of the intermediate can react with nitrite and its sodium salt to form heavy nitrogen salt. The nitro group in molecular structure can be reduced, and the sulfonic acid group can be replaced by another group, deriving various key intermediates.

Application

The product is mainly applied into synthesis of dyes and organic dyes, which is an important intermediate for organic pigments. With it as a heavy nitrogen component, the C.I pigment yellow 133, 168, 169, 61, 62 and other categories can be obtained.
