Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1,4-Dioxo-1,3a,4,5-tetrahydropentalen-3a-yl hydrogen sulfate (CAS 108347-23-5), molecular formula C8H6O6S and molecular weight 230.19 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,4-Dioxo-1,3a,4,5-tetrahydropentalen-3a-yl hydrogen sulfate (C8H6O6S) is characterized by a sulfone 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).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
