Chemical Structure
Description
The occurrence of iso-PPADS Tetrasodium Salt is closely related to a flavonoid core, an amide group, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
iso-PPADS Tetrasodium Salt (CAS 207572-67-6) is a high-purity analytical reference standard with the molecular formula C15H14N3O11PS2Na and a molecular weight of 530.37 g/mol.
The molecular framework of iso-PPADS Tetrasodium Salt (C15H14N3O11PS2Na) is characterized by a flavonoid core, an amide group, a sulfone group, a phosphate ester group, a hydroxyl 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), iso-PPADS 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.
