For scientists and formulators in the chemical and imaging sectors, a deep understanding of the properties of key intermediates is essential for successful product development. Color Developing Agent CD-2 (CAS 2051-79-8) is a critical component in photographic and printing applications, and its specific chemical and physical characteristics dictate its performance and handling requirements. This article delves into these vital details.

Color Developing Agent CD-2, chemically known as 4-(N,N-Diethyl)-2-methyl-p-phenylenediamine monohydrochloride, presents itself as a white crystalline powder. Its molecular formula, C11H19ClN2, and molecular weight, 214.73500, are fundamental identifiers. A key aspect for formulators is its solubility; CD-2 is readily soluble in water, forming solutions that are typically colorless to light red when freshly prepared. However, it is prone to oxidation in the air, which can lead to a deepening of color, emphasizing the need for controlled storage and handling by manufacturers and end-users alike.

The functional properties of CD-2 are equally important. It is widely employed as a high-temperature rapid developer, a crucial role in the processing of oil-soluble color films. In this capacity, it facilitates the transformation of latent images into stable, visible color images. The specifications provided by reputable suppliers often include parameters such as volatile matter (typically ≤0.1%), pH range (5.2-5.5 for a 5% water solution), and a defined melting point range (126-131℃). Adherence to these specifications is vital for consistent results when you purchase this chemical.

Furthermore, the ash content (≤0.1%) and heavy metal content (≤0.001%) are critical indicators of purity, which directly impacts the agent's effectiveness and suitability for sensitive applications. The photographic properties are qualified, confirming its readiness for use in industrial imaging processes. For those looking to buy Color Developing Agent CD-2, understanding these detailed specifications from suppliers and manufacturers is paramount to ensure the desired outcome in their formulations. Researching the chemical properties of CAS 2051-79-8 will guide you in selecting the right product and supplier.

In summary, the specific chemical and physical properties of Color Developing Agent CD-2 are central to its utility in the photographic and printing industries. By understanding its solubility, reactivity, purity levels, and handling requirements, R&D scientists and procurement managers can make informed decisions when sourcing this important chemical intermediate. Always consult with trusted manufacturers for detailed product information and technical support.
