Description
1(2),3(2),5(2),7(2)-Tetrahydroxy-1,3,5,7(1,3)-tetrabenzenacyclooctaphane-1(5),3(5),5(5),7(5)-tetrasulfonic acid, sodium salt (CAS 151657-13-5), molecular formula C28H24O16S4Na and molecular weight 767.71 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1(2),3(2),5(2),7(2)-Tetrahydroxy-1,3,5,7(1,3)-tetrabenzenacyclooctaphane-1(5),3(5),5(5),7(5)-tetrasulfonic acid, sodium salt (C28H24O16S4Na) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 17.0, corresponding to approximately 17 ring(s) or double-bond equivalent(s). With a molecular weight of 767.71 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
