Product Overview

• 4-Hydroxy-2H-Chromen-2-One, widely designated across industrial and pharmaceutical networks as 4-Hydroxycoumarin, is a premier organic intermediate compound. It acts as a critical molecular scaffold for developing advanced anticoagulant medications and high-efficiency rodenticide actives. Commercially supplied as a fine, off-white to light yellow crystalline solid powder, it delivers excellent solubility parameters across common organic solvent bases. ProCorBay International distributes exceptional, high-purity 4-Hydroxycoumarin to global pharmaceutical synthesis plants, agrochemical blending operations, and custom chemical research teams.
• 4-Hydroxycoumarin is manufactured through the intramolecular condensation of o-acetylsalicoyl chloride or via the reaction of methyl salicylate with sodium metal, followed by acid precipitation and multi-step recrystallization. ProCorBay coordinates active distribution chains with advanced specialty chemical synthesis operations to supply product streams featuring low total moisture parameters and high active chemical assays. 
• Within the life sciences and agricultural domains, this benzopyran derivative is highly valued for its unique biological interaction mechanism. It serves as the primary starting block for synthesizing blockbuster vitamin K antagonists, including Warfarin, Phenprocoumon, and Acenocoumarol. The hydroxy modification on the coumarin ring system allows for easy chemical substitution, helping formulators attach functional organic groups smoothly. ProCorBay maintains robust, year-round inventory lanes to ensure seamless supply continuity for your chemical processing configurations.
