59457-26-0 1-Chloro-1,2-benziodoxol-3-one MFCD28411322 NSC191950/ 1-chloro-1lambda3,2-benziodoxol-3(1H)-one (CAS 59457-26-0), molecular formula C7H4ClIO2 and molecular weight 282.46 g/mol, is a CATO reference standard with documented purity and traceability.

59457-26-0 1-Chloro-1,2-benziodoxol-3-one MFCD28411322 NSC191950/ 1-chloro-1lambda3,2-benziodoxol-3(1H)-one (C7H4ClIO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 59457-26-0 1-Chloro-1,2-benziodoxol-3-one MFCD28411322 NSC191950/ 1-chloro-1lambda3,2-benziodoxol-3(1H)-one 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.
