Description
As a certified reference material (CRM), 4,4＇-Bis(diethylamino)benzophenone 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.
4,4＇-Bis(diethylamino)benzophenone (CAS 90-93-7), molecular formula C21H28N2O and molecular weight 324.46 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4,4＇-Bis(diethylamino)benzophenone (C21H28N2O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 324.46 g/mol, it falls into the moderately-high-molecular-weight range. 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.
