Chemical Structure
Description
N-(4-Ethoxyphenyl)-4-isothiocyanatobenzenesulfonamide (CAS 100970-00-1), molecular formula C15H14N2O3S2 and molecular weight 334.41 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, N-(4-Ethoxyphenyl)-4-isothiocyanatobenzenesulfonamide (C15H14N2O3S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, 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 334.41 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.
As a certified reference material (CRM), N-(4-Ethoxyphenyl)-4-isothiocyanatobenzenesulfonamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
