Chemical Structure
Description
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.
2-[({[(E)-(3-nitrophenyl)methylidene]amino}oxy)carbonyl]furan 303987-12-4 KS-00001S0O (CAS 303987-12-4), molecular formula C12H8N2O5 and molecular weight 260.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-[({[(E)-(3-nitrophenyl)methylidene]amino}oxy)carbonyl]furan 303987-12-4 KS-00001S0O (C12H8N2O5) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
As a certified reference material (CRM), 2-[({[(E)-(3-nitrophenyl)methylidene]amino}oxy)carbonyl]furan 303987-12-4 KS-00001S0O 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.
