Chemical Structure
Description
2,2-biphenylÂdiolÂ, cyclic phosphate (CAS 35227-84-0) is a high-purity analytical reference standard with the molecular formula C12H9O4P and a molecular weight of 248.17 g/mol.
2,2-biphenylÂdiolÂ, cyclic phosphate (C12H9O4P) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2,2-biphenylÂdiolÂ, cyclic phosphate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
