Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 224.24 g/mol gives 8-Aminoquinoline-5-sulfonic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
8-Aminoquinoline-5-sulfonic acid (CAS 41606-26-2), molecular formula C9H8N2O3S and molecular weight 224.24 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 8-Aminoquinoline-5-sulfonic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 224.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
