Description

Butanedioic acid, 2-((6-oxido-6H-dibenz(c,e)(1,2)oxaphosphorin-6-yl)methyl)-, 1,4-bis(2-hydroxyethyl) ester (CAS: 63562-34-5) is a high-purity organophosphorus compound with the molecular formula C₂₁H₂₃O₈P. This specialized chemical features a dibenzoxaphosphorin core modified with a succinate ester and hydroxyethyl functional groups, offering unique reactivity and solubility properties. The compound is supplied as a white to off-white crystalline powder with ≥95% purity (HPLC), packaged under inert gas to ensure stability. It is soluble in common organic solvents such as DMSO, THF, and dichloromethane but has limited water solubility. This product is ideal for researchers developing flame retardant additives, polymer modifiers, or specialty phosphorous-containing ligands for catalytic systems. Each batch is QC-tested by GC-MS and ¹H/³¹P NMR to guarantee structural identity and purity.

Application

This organophosphorus compound serves as a reactive intermediate in flame retardant formulations, where its phosphorus content and hydroxyl groups enable covalent incorporation into polymers. Researchers utilize it as a building block for synthesizing novel phosphorus-containing dendrimers and hyperbranched polymers with potential applications in flame-resistant coatings. The compound’s bifunctional nature also makes it valuable for developing crosslinkable epoxy resin systems with enhanced thermal stability.
