Chemical Structure
Description
As a certified reference material (CRM), N1-(2,4-Dinitrophenyl)ethane-1,2-diamine 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.
N1-(2,4-Dinitrophenyl)ethane-1,2-diamine (CAS 28767-75-1), molecular formula C8H10N4O4 and molecular weight 226.19 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, N1-(2,4-Dinitrophenyl)ethane-1,2-diamine (C8H10N4O4) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 226.19 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).
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.
