For industrial buyers, procurement decisions are driven by a blend of quality, cost, availability, and supplier reliability. When it comes to essential chemical additives like UV absorbers, these factors become even more critical. This guide focuses on 2,4-Dihydroxybenzophenone (CAS 131-56-6), a widely used UV absorber, outlining the key considerations for businesses looking to make a strategic purchase from manufacturers and suppliers, particularly those in China.

The primary consideration when buying 2,4-Dihydroxybenzophenone is quality. This compound's effectiveness as a UV absorber is directly linked to its purity and consistency. Buyers should prioritize products with a high assay, typically 99% min, as indicated by HPLC analysis. Reputable manufacturers will readily provide Certificates of Analysis (COA) detailing key specifications such as melting point (ideally 142-146°C), loss on drying, ash content, and heavy metal limits. These parameters are crucial indicators of the product's quality and suitability for specific applications. For R&D scientists and product formulators, ensuring these specifications are met is fundamental to achieving desired product performance and stability.

Understanding the product's physical characteristics is also important. 2,4-Dihydroxybenzophenone is typically supplied as a white or light yellow crystalline powder. Variations in appearance or an inconsistent particle size can sometimes indicate processing issues or contamination. Buyers should consult with their potential supplier about packaging options, which can range from 25kg cardboard drums to specialized bulk containers, ensuring the product remains protected and stable during storage and transportation.

When sourcing from China, it is vital to partner with a manufacturer or supplier that demonstrates a strong commitment to customer service and a reliable supply chain. Look for companies with established production capacities, responsive communication channels, and experience in international logistics. Suppliers who can offer technical support, assist with product inquiries, and provide timely quotations are invaluable partners. For example, inquiring about lead times for both standard and custom orders is a wise procurement strategy.

The price is, of course, a significant factor. However, it should always be considered in conjunction with quality and reliability. Purchasing the cheapest option without verifying its specifications can lead to costly product failures and reputational damage. A competitive price from a trusted manufacturer, backed by consistent quality and dependable delivery, represents the best value for industrial buyers.
