The cosmetic industry, particularly the segment focused on hair coloring, relies heavily on high-quality chemical intermediates to ensure product performance, safety, and consistency. Among these critical components is 2,6-Diaminopyridine sulfate, a vital compound serving as a key intermediate in the synthesis of various hair dye formulations. Its unique chemical structure contributes to the desired color properties and stability of the final hair coloring products.

Known by its CAS Number 146997-97-9 and synonyms such as Pyridine-2,6-diamine sulfate, this chemical is an off-white crystalline powder. Its molecular formula is C5H9N3O4S, with a molecular weight of 207.20800. As an intermediate, the purity and consistency of 2,6-Diaminopyridine sulfate are paramount. Impurities can lead to unpredictable reactions, undesirable side colors, or reduced shelf life of hair dye products, potentially causing irritation or other adverse effects.

Meeting stringent quality specifications is therefore non-negotiable for reliable supply. Key specifications for high-quality 2,6-Diaminopyridine sulfate include:
Appearance: Off-white crystalline powder
Purity (HPLC): ≥99.0%
Ash: ≤0.5%
Loss on drying: ≤0.5%
Fe content: ≤100ppm

A purity level of 99.0% or higher, verified by HPLC, indicates minimal levels of related substances and reaction byproducts, which is crucial for performance in sensitive cosmetic applications. Low ash and loss on drying values ensure minimal inorganic residues and moisture content, contributing to the stability and ease of handling of the material. A controlled low iron content is particularly important as trace metals can sometimes interfere with dye chemistry or affect color outcomes.

The primary application of this compound lies in its role within hair dye formulations. It serves as a building block, reacting with other chemicals to create the complex molecules responsible for depositing semi-permanent or permanent color onto hair fibers. Its specific pyridine structure and amino groups are essential for the desired chemical reactions and color properties. Ensuring a consistent and high-quality supply of this intermediate is thus fundamental for manufacturers of hair coloring products globally.

Packaging typically involves 25 kg drums, although suppliers often accommodate specific customer packaging requirements. Proper storage is also critical to maintain product integrity; storing in a cool, ventilated place away from moisture and incompatible materials is recommended to prevent degradation.

For cosmetic companies and chemical manufacturers seeking a reliable source for this essential raw material, finding a reputable manufacturer and supplier is key. Sourcing directly from manufacturers with robust quality control systems ensures the purity and consistency required for high-performance hair dye products. Companies interested in obtaining more information, including competitive price details and procedures on how to buy or purchase high-quality 2,6-Diaminopyridine sulfate, are encouraged to inquire directly to secure their supply chain of this vital intermediate for the hair color industry.
