The occurrence of Diquafosol Impurity 20 is closely related to a carbohydrate-derived structure, an amide group, a phosphate ester group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Diquafosol Impurity 20 (CAS 2922-94-3), molecular formula C9H15N3O11P2 and molecular weight 403.18 g/mol, is a CATO reference standard with documented purity and traceability.
Diquafosol Impurity 20 (C9H15N3O11P2) contains a carbohydrate-derived structure, an amide group, a phosphate ester group. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
CATO manufactures Diquafosol Impurity 20 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
