Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Diquafosol Tetrasodium Salt.
Diquafosol Tetrasodium Salt (CAS 211427-08-6), molecular formula C18H22N4O23P4Na and molecular weight 809.26 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Diquafosol Tetrasodium Salt (C18H22N4O23P4Na) is characterized by a flavonoid core, an amide group, a phosphate ester group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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), Diquafosol Tetrasodium Salt 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.
