Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 366.34 g/mol gives 4-(Diethylamino)benzenesulfonic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-(Diethylamino)benzenesulfonic acid (CAS 35478-73-0), molecular formula C16H14O8S and molecular weight 366.34 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-(Diethylamino)benzenesulfonic acid (C16H14O8S) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 366.34 g/mol, it falls into the moderately-high-molecular-weight range. 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.
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.
