Chemical Structure
Description
The occurrence of Pyrene-1,3,6,8-tetrasulphonic acid is closely related to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Pyrene-1,3,6,8-tetrasulphonic acid (CAS 6528-53-6) is a high-purity analytical reference standard with the molecular formula C16H10O12S4 and a molecular weight of 522.50 g/mol.
The molecular framework of Pyrene-1,3,6,8-tetrasulphonic acid (C16H10O12S4) is characterized by a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage. 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).
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), Pyrene-1,3,6,8-tetrasulphonic acid 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.
