For manufacturers in the cosmetic and chemical industries, the sourcing of reliable and high-purity raw materials is foundational to product success. NINGBO INNO PHARMCHEM CO.,LTD. specializes in providing essential chemical intermediates, including 4-nitro-o-phenylenediamine, a critical component in the 'hair dye chemistry' sector. This article outlines why specifying high-purity 4-nitro-o-phenylenediamine is crucial for achieving optimal results and meeting market demands.

The compound, identified by its CAS number 99-56-9, is known by several names including 4-nitrobenzene-1,2-diamine and 4-nitro-o-phenylenediamine. Its role as a 'hair dye intermediate' means that even minor impurities can significantly impact the final color's shade, stability, and safety profile. Therefore, when companies decide to 'buy 4-nitro-o-phenylenediamine online', they must prioritize suppliers who guarantee stringent quality control and high purity levels. NINGBO INNO PHARMCHEM CO.,LTD. ensures its product meets the '4-nitro-o-phenylenediamine hair dye intermediate' standard with a minimum purity of 99.0% (HPLC).

The 'synthesis of 4-nitro-1,2-phenylenediamine' is a precise process that requires careful handling of raw materials and reaction parameters. Manufacturers often seek suppliers who not only provide the chemical but also possess robust quality assurance systems. The low ash content (≤0.5%) and minimal loss on drying (≤0.5%) of our product are critical indicators of its quality. These specifications minimize unwanted side reactions and ensure that the intended colorimetric properties of the 'uses of 4-nitro-o-phenylenediamine' are fully realized.

The 'properties of 4-nitrobenzene-1,2-diamine' are also vital considerations. Its appearance as an orange-red crystalline powder and its stable melting point (199-201°C) make it easy to handle and incorporate into various formulations. The chemical's overall stability, indicated by its high boiling point and flash point, adds to its safety profile during processing.
