Diethyl ((benzyloxy)methyl)phosphonate (CAS 89268-01-9), molecular formula C12H19O4P and molecular weight 258.25 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Diethyl ((benzyloxy)methyl)phosphonate (C12H19O4P) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 258.25 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), Diethyl ((benzyloxy)methyl)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.
