For any manufacturer involved in the production of advanced electronic materials, securing a consistent and high-quality supply of key chemical intermediates is non-negotiable. This is particularly true when it comes to photoresist chemicals, where minute impurities can have a significant impact on the final product's performance. One such compound that plays a vital role in certain photoresist formulations is 4H-1-Benzopyran-4-one,3,7-dihydroxy-2-(3,4,5-trihydroxyphenyl)-, identified by its CAS number 490-31-3, and often referred to by its common name, Robinetin.

As a manufacturer specializing in electronic chemicals, our focus is on providing reliable access to compounds like CAS 490-31-3. We understand that our B2B customers, including R&D scientists and procurement managers, require not just a chemical, but a solution that ensures operational efficiency and product integrity. When you choose to buy this specific photoresist chemical from us, you are engaging with a supplier that prioritizes purity, consistency, and competitive pricing. Our manufacturing processes in China are optimized to produce 4H-1-Benzopyran-4-one,3,7-dihydroxy-2-(3,4,5-trihydroxyphenyl)- with the rigorous quality standards demanded by the electronics industry.

The chemical properties of Robinetin, such as its molecular formula C15H10O7 and molecular weight of 302.25, along with its physical characteristics like density (1.799 g/cm³) and high boiling point (669.9 °C), make it a valuable ingredient for photoresist formulations. We ensure that each batch meets these specifications, preventing costly production errors and enabling the creation of high-resolution patterns essential for microelectronics. Our role as a manufacturer means we have direct control over the production process, from raw material sourcing to final product inspection, guaranteeing the quality of 3,7,3',4',5'-Pentahydroxyflavone.
