When sourcing chemical intermediates, understanding the critical specifications is paramount for ensuring product quality, performance, and safety. For 2,5-Diaminotoluene Sulfate (CAS 615-50-9), a key ingredient in the hair dye industry, a discerning buyer must look beyond just the product name and CAS number. As a leading hair dye intermediate manufacturer, we believe in transparency and providing our clients with the knowledge to make informed purchasing decisions.

What are the Essential Specifications for 2,5-Diaminotoluene Sulfate?

When you buy 2,5-Diaminotoluene Sulfate, here are the key parameters you should verify with your potential 2,5-Diaminotoluene Sulfate supplier:

  1. Appearance: This specification describes the physical state and color of the compound. For 2,5-Diaminotoluene Sulfate, the standard appearance is typically a White crystalline powder. Any significant deviation from this may indicate impurities or improper handling.
  2. Purity (Assay): This is arguably the most critical specification. Purity is usually determined by High-Performance Liquid Chromatography (HPLC). For cosmetic applications, a high purity level, such as ≥99.5% (HPLC), is often required to ensure consistent performance and predictable color development in hair dyes.
  3. Ash Content: Ash content refers to the inorganic residue left after the organic material has been burned off. A low ash content, typically ≤0.2%, signifies minimal inorganic impurities, which is important for product purity and formulation stability.
  4. Loss on Drying (LOD): This measures the amount of moisture present in the sample. Low moisture content, usually ≤0.2%, is essential for product stability, shelf life, and accurate weighing during formulation processes.
  5. Iron (Fe) Content: Iron can sometimes catalyze unwanted reactions or affect color stability. Specifications often limit iron content to a very low level, such as ≤20ppm.
  6. Heavy Metal Content: Due to its use in cosmetic products, stringent limits are placed on heavy metals (e.g., lead, arsenic, mercury). A typical specification might be ≤10ppm for total heavy metals.

Why These Specifications Matter to You

For R&D Scientists: High purity and low impurity levels ensure reproducible results in formulation development and testing. Consistent specifications allow for accurate prediction of how the intermediate will perform in various chemical reactions and cosmetic matrices.

For Procurement Managers: Verifying these specifications helps in comparing quotes from different suppliers and selecting one that offers the best balance of price and quality. Understanding these details allows you to ensure you are purchasing a material that meets industry standards and regulatory requirements, mitigating risks associated with substandard products.
