Calmagite triethanolammonium salt (CAS 91698-30-5), molecular formula C17H13N2O5SC6H16NO3 and molecular weight 507.56 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Calmagite triethanolammonium salt (C17H13N2O5SC6H16NO3) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 507.56 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.
