CD-4 Color Developer Supplier | CAS 25646-77-9
Product Introduction
CD-4 color developer (CAS 25646-77-9) is a chemical developing agent used in color photographic processing. Its chemical name is 4-(N-Ethyl-N-2-hydroxyethyl)-2-methylphenylenediamine sulfate. It plays an important role in color development by helping form image dyes during the photographic development process.
For buyers sourcing CD-4 for industrial or photographic applications, product identity, quality specifications, and batch documentation are important considerations. The supplied material should match the required grade and the specifications agreed upon with the supplier.
Applications of CD-4 Color Developer
1. Color Photographic Processing
CD-4 is used in color photographic development systems, including C-41 color negative film processing. During development, the oxidized developing agent reacts with color couplers to form image dyes.
2. Photographic Chemical Formulations
CD-4 can be used as a raw material in the preparation of photographic developer solutions. The final formulation and processing conditions should follow the requirements of the intended photographic system.
3. Industrial Photographic Applications
Manufacturers and formulators may source CD-4 for photographic chemical production. Before adopting a new batch or supplier, buyers should confirm product specifications and evaluate its performance under relevant process conditions.

What to Check When Purchasing CD-4?
Product Identity and Specifications
Confirm the CAS number, chemical name, and supplied form before ordering. Do not rely on the product name alone when comparing quotations from different suppliers.
Quality Documentation
Request the available Certificate of Analysis (COA), Technical Data Sheet (TDS), and Safety Data Sheet (SDS). Review the assay, test methods, appearance, and other agreed quality parameters.
Batch Consistency
For repeat purchases, compare the quality documents for each batch. If the material is used in a critical process, conduct an application test before approving a new supplier or changing the source.
Packaging and Delivery
Confirm packaging, minimum order quantity, lead time, storage requirements, and shipping arrangements before placing an order. These details help you evaluate the total purchasing cost and plan your inventory.

FAQ
CD-3 has strong versatility and is suitable for low temperatures; CD-4 has higher activity, high temperature resistance, and brighter colors. It is specifically suitable for high-temperature rapid processing technology of color film and photo paper. CD-4 is preferred for film and industrial photosensitive materials.
Conventional HPLC ≥ 98.0%, photosensitive grade can reach 99%; Strictly control impurities and chromaticity to ensure that the image does not have color cast, low haze, and stable layering, meeting the standards of film printing cinemas.
The reduction of silver halide precipitates metallic silver, which oxidizes itself and couples with colorants to generate color dyes. It accurately restores the red/green/blue three-layer colors and is a key agent for color film imaging.
Escrow and T/T in advance are highly recommended. We can accept Western Union, Money Gram and Paypal as well.
