4-(N-Ethyl-N-2-hydroxyethyl)-2-methylphenylenediamine sulfate, widely known as CD-4, is a chemical compound with specific properties that dictate its use and handling. Understanding these chemical developer CD-4 properties is essential for anyone working with this substance, whether in photographic processing or research applications.

Physically, CD-4 typically presents as a beige fine crystalline powder. This form is stable under recommended storage conditions, usually at room temperature and in an inert atmosphere. The compound has a melting point of 155°C, a key characteristic for identifying its purity and for process control during its application. Its solubility in water is also an important factor for its use in aqueous-based photographic development solutions.


Crucially, CD-4 is recognized as a potential allergen and irritant, particularly to the skin and respiratory system. This necessitates strict adherence to safety protocols when handling the material. Personal protective equipment (PPE), such as gloves, eye protection, and appropriate respiratory masks, should always be used. Information regarding its hazard codes (T, N, Xi) and risk statements (e.g., R25, R43, R48/22, R50/53) underscores the importance of safe handling practices and proper disposal. Consulting the full Safety Data Sheet (SDS) is a fundamental step for any user.


For manufacturers and users alike, understanding these chemical properties and hazards is integral to its effective and safe application. Whether you are leveraging it for its photographic chemical solutions or its role in chemical synthesis for imaging, a thorough knowledge of CD-4’s characteristics ensures optimal results and workplace safety.
