Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including dimethyl 2-((4R,5S)-5-(2-(benzyloxy)acetyl)-2,2-dimethyl-1,3-dioxolan-4-yl)-2-oxoethylphosphonate.
dimethyl 2-((4R,5S)-5-(2-(benzyloxy)acetyl)-2,2-dimethyl-1,3-dioxolan-4-yl)-2-oxoethylphosphonate (CAS 89291-74-7), molecular formula C18H25O8P and molecular weight 400.36 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of dimethyl 2-((4R,5S)-5-(2-(benzyloxy)acetyl)-2,2-dimethyl-1,3-dioxolan-4-yl)-2-oxoethylphosphonate (C18H25O8P) is characterized by a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), dimethyl 2-((4R,5S)-5-(2-(benzyloxy)acetyl)-2,2-dimethyl-1,3-dioxolan-4-yl)-2-oxoethylphosphonate 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.
