The world of photography and advanced imaging relies on a precise orchestration of chemical reactions to bring images to life. Among the critical components is 4-(N-Ethyl-N-2-hydroxyethyl)-2-methylphenylenediamine sulfate, commonly known as CD-4.

CD-4 is a vital color film developer, essential for achieving the rich and accurate colors we associate with professional photography. Its application spans across well-established processes like Kodacolor II, Flexicolor, and the C-41 process, which are the backbone of color negative film development. The ability of CD-4 to facilitate the formation of dyes within the photographic emulsion is what ultimately creates the final colored image. Understanding the chemical synthesis for imaging is key to appreciating its significance.


Beyond traditional photography, CD-4 plays a crucial role in specialized scientific fields, particularly in color microautoradiography. Here, it is used for the color development of immunogold-labeled antibodies. This application is critical for researchers visualizing cellular structures and biological processes at a microscopic level, highlighting the compound's versatility and importance in research settings. For those in this field, finding CD-4 suppliers China can be a strategic move for cost-effective sourcing without compromising on quality.


While highly effective, it's important for photographers and laboratory technicians to be aware that CD-4 can be both an allergen and an irritant. Proper handling procedures and safety precautions, as detailed in its chemical developer CD-4 properties, are paramount. This includes understanding its beige, fine crystalline powder form and its melting point of 155°C, which inform storage and handling best practices.


For businesses and researchers requiring this compound, sourcing from reputable manufacturers is key. The advantages of using CD-4 include its exceptional color fidelity and its reliable performance in various applications. By partnering with trusted chemical manufacturers, you can ensure a consistent supply of high-quality CD-4, supporting your photographic chemical solutions and advanced research needs.
