For businesses in the cosmetics sector, particularly those focusing on hair color products, the quality and reliability of chemical intermediates are paramount. Among these crucial components is 4-Nitro-1,3-phenylenediamine Sulfate, a compound widely utilized for its efficacy in dye synthesis. This article aims to guide procurement managers and R&D scientists in understanding what to look for when sourcing such essential raw materials from global manufacturers.

Understanding the Role of 4-Nitro-1,3-phenylenediamine Sulfate
4-Nitro-1,3-phenylenediamine Sulfate, identified by CAS No. 200295-57-4, serves as a foundational building block in the creation of various hair dye formulations. Its chemical structure, C6H9N3O6S, allows for the development of specific color shades and ensures color stability upon application. For any cosmetic manufacturer, securing a consistent supply of this intermediate with high purity is a critical step towards producing high-quality, marketable hair color products.

Key Quality Indicators for Hair Dye Intermediates
When evaluating potential suppliers, several key specifications for 4-Nitro-1,3-phenylenediamine Sulfate should be scrutinized. The appearance, typically a yellow crystalline powder, is a primary visual check. More importantly, purity levels, often specified as ≥99.0% via HPLC, directly impact the performance and predictability of the final dye product. Moisture content, ideally ≤0.5%, is also vital for ensuring the stability and shelf-life of the intermediate and the finished cosmetic product. Manufacturers and R&D chemists should prioritize suppliers who provide detailed Certificates of Analysis (CoA) that clearly state these specifications.

How to Select a Reliable Chemical Manufacturer and Supplier
For procurement managers seeking to buy 4-Nitro-1,3-phenylenediamine Sulfate, choosing a reputable manufacturer and supplier is crucial for ensuring product quality and supply chain stability. Consider factors such as:

  • Manufacturing Capacity and Consistency: Does the supplier have the infrastructure to meet your volume requirements consistently?
  • Quality Control Processes: Do they adhere to strict quality assurance protocols throughout their manufacturing?
  • Technical Support: Can they provide technical assistance for formulation or application challenges?
  • Logistics and Export Capabilities: Are they experienced in international shipping and compliance?
  • Price and Value: While competitive pricing is important, ensure it does not compromise quality. Obtaining a quote from a trusted supplier often reveals the true value.
