In the complex landscape of industrial chemical sourcing, precise identification and consistent quality are non-negotiable. The Chemical Abstracts Service (CAS) Registry Number serves as a unique identifier for chemical substances, ensuring that procurement professionals and researchers are consistently referring to the same compound. For a vital material like UV Absorber 531, its CAS number, 1843-05-6, is a critical piece of information for accurate sourcing and quality assurance.

UV Absorber 531, also known by its chemical name Octabenzone or trade names like Cyasorb UV-531, is a highly effective light stabilizer used extensively across industries such as plastics, coatings, and rubber. Its primary function is to protect polymers and other materials from degradation caused by ultraviolet (UV) radiation, thereby extending their lifespan and preserving their aesthetic and mechanical properties. The CAS number 1843-05-6 ensures that regardless of the various synonyms or trade names used, buyers are consistently specifying the same chemical compound with its unique properties and intended applications.

For purchasing managers and R&D scientists, verifying the CAS number is a fundamental step in the supplier qualification process. It helps filter out substandard or misidentified products and ensures that the material procured meets the required purity and performance standards. When searching for UV Absorber 531, using CAS 1843-05-6 will lead you to a more targeted list of manufacturers and distributors who specialize in this specific chemical.

Finding a reliable supplier for a crucial chemical like UV Absorber 531 often involves looking for manufacturers with robust quality control systems, consistent production capacity, and competitive pricing. Companies that clearly display the CAS number 1843-05-6 alongside detailed product specifications are generally more transparent and trustworthy. Whether you are looking to purchase in bulk for manufacturing or require smaller quantities for research, always prioritize suppliers who can confidently provide documentation and support related to the CAS number 1843-05-6, ensuring your applications receive the intended UV protection and performance.
