Description
As a certified reference material (CRM), N-Ethyl-N-(2-nitrophenyl)methanesulfonamide 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.
N-Ethyl-N-(2-nitrophenyl)methanesulfonamide (CAS 195433-52-4), molecular formula C9H12N2O4S and molecular weight 244.27 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, N-Ethyl-N-(2-nitrophenyl)methanesulfonamide (C9H12N2O4S) 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 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 244.27 g/mol, it falls into the medium-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.
