Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Bis[2,4-bis(1,1-dimethylethyl)phenyl] phosphonate.
Bis[2,4-bis(1,1-dimethylethyl)phenyl] phosphonate (CAS 73640-91-2) is a high-purity analytical reference standard with the molecular formula C28H43O3P and a molecular weight of 458.61 g/mol.
Bis[2,4-bis(1,1-dimethylethyl)phenyl] phosphonate (C28H43O3P) contains a steroid core, a phosphonate group, a hydroxyl group, an ether linkage. 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), Bis[2,4-bis(1,1-dimethylethyl)phenyl] phosphonate 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.
