The magic of color photography lies in a complex interplay of chemistry and light. At the heart of this process is the color developer, and one of the most important is N,N-Diethyl-p-phenylenediamine sulfate, widely recognized as CD-1. For photographic labs and chemical buyers, understanding the role of this compound and ensuring its quality is fundamental. This article explores the chemistry of CD-1 and guides procurement professionals on how to buy effectively from reliable manufacturers.

N,N-Diethyl-p-phenylenediamine sulfate (CAS 6283-63-2) functions as a primary color developing agent. In a color photographic film, silver halide crystals are exposed to light, capturing the image. During development, CD-1 selectively reduces the exposed silver halide, and in doing so, it undergoes oxidation. This oxidized form then couples with dye-forming color couplers embedded in the film layers, producing the dyes that form the visible color image. The specific chemical structure of CD-1 is engineered to facilitate these reactions efficiently and predictably.

The performance of CD-1 is highly dependent on its purity. Impurities can lead to unpredictable color shifts, reduced image contrast, or even fogging of the film. Therefore, photographic professionals must buy from manufacturers that guarantee a high assay, typically 99.0% or higher, along with low levels of critical impurities. As a leading manufacturer and supplier of fine chemicals, we understand these stringent requirements and are dedicated to producing N,N-Diethyl-p-phenylenediamine sulfate that consistently meets them. We are your trusted source for photographic grade chemicals.

Procurement managers in the photographic industry will find that partnering with a consistent supplier is key. Sourcing CD-1 from a reliable manufacturer ensures not only product quality but also the stability of your supply chain. This means fewer disruptions in production and consistent output quality. When you choose to buy N,N-Diethyl-p-phenylenediamine sulfate from us, you are assured of a product that has undergone rigorous quality control, making it ideal for all your color photographic needs.
