The chemical industry's progress is often marked by the development and reliable supply of key intermediates that enable innovation in downstream products. For the dyes and pigments sector, compounds like 1-(2'-Chloro-5'-sulfophenyl)-3-methyl-5-pyrazolone, identified by its CAS number 88-76-6, are foundational. This article explores the significance of this specific pyrazolone derivative for industry professionals looking to buy essential materials for their production processes.

CAS 88-76-6 serves a critical function as a coupling component in the synthesis of a wide array of organic dyes and pigments. Its chemical structure allows it to react with diazonium salts, forming azo dyes, which are known for their bright colors and diverse applications. The presence of the sulfophenyl group also imparts water solubility and can influence the lightfastness of the final colorant. For professionals in the field, understanding that this compound is a primary building block for vibrant and stable colors is key to effective product development. Ensuring access to a consistent supplier is therefore paramount.

When evaluating sources, the purity of CAS 88-76-6 is a non-negotiable aspect. A typical specification of ≥98.0% purity is essential for achieving reproducible results in complex organic syntheses. This intermediate’s physical state as a light yellow crystalline powder also offers practical advantages in handling and incorporation into manufacturing workflows. Furthermore, its notable thermal stability, indicated by a high melting point of 344°C, makes it suitable for processes that involve elevated temperatures, a common scenario in the synthesis of robust colorants used in industrial applications.

For businesses aiming to optimize their procurement strategy, identifying reliable manufacturers, particularly those based in China, can offer significant advantages in terms of cost and supply chain efficiency. When you purchase 1-(2-chloro-5-sulfophenyl)-3-methyl-5-pyrazolone, engaging with a reputable supplier in China ensures that you not only receive a high-quality product but also benefit from established logistics and competitive pricing. This strategic sourcing helps maintain production continuity and allows for competitive product offerings in the global market. Accessing expertise from such suppliers can also provide valuable insights into optimal usage and handling.
