The quest for perfect hair color is a continuous journey, driven by consumer desires for vibrancy, longevity, and safety. Central to achieving these goals is the sophisticated chemistry employed in hair dye formulations. NINGBO INNO PHARMCHEM CO.,LTD. is at the forefront of providing key chemical intermediates that form the backbone of these advanced products, with 1,3-Bis(2,4-Diaminophenoxy)Propane 4HCl (CAS 74918-21-1) being a prime example.

Understanding the chemical nature of 1,3-Bis(2,4-Diaminophenoxy)Propane 4HCl is crucial to appreciating its role. Its molecular formula, C15H24Cl4N4O2, and molecular weight of 434.18900 highlight a complex structure designed for specific chemical reactions. As a hair dye intermediate, it contains multiple amino groups, which are essential for participating in the oxidative coupling reactions that create permanent hair color. These reactions involve the formation of chromophores (color-bearing molecules) within the keratin structure of the hair shaft. The result is a color that is deeply integrated and highly resistant to fading, wash after wash. This makes the precise formulation and high purity of this intermediate indispensable for manufacturers.

The physical and chemical properties of 1,3-Bis(2,4-Diaminophenoxy)Propane 4HCl are rigorously controlled during its production. Typically supplied as an off-white to white powder, it is easily manageable in industrial settings. Key specifications, such as a melting point of 215°C, a boiling point of 643.9°C, and a flash point of 343.2°C, indicate its thermal stability and relative safety under typical processing conditions. Furthermore, the purity, verified by HPLC to be ≥99.0%, along with low ash content (≤0.5%) and minimal loss on drying (≤0.5%), ensures that the intermediate performs predictably and consistently. These parameters are meticulously monitored by NINGBO INNO PHARMCHEM CO.,LTD. to guarantee that our clients receive only the highest quality product.

The primary application of 1,3-Bis(2,4-Diaminophenoxy)Propane 4HCl is as a vital component in permanent hair dye formulations. It functions as a coupler, reacting with primary intermediates (developers) in the presence of an oxidizing agent (like hydrogen peroxide) to form the final color. The specific arrangement of functional groups within the molecule influences the final shade and its intensity, allowing formulators to achieve a wide palette of colors. Its ability to create strong, stable bonds within the hair fiber is what provides the long-lasting effect that consumers desire. This makes it a critical ingredient for any brand committed to delivering superior hair coloring experiences.
