Chemical Structure
Description
2-((2-Hydroxyethyl)amino)-5-nitrophenol2- (CAS 73388-54-2) is a high-purity analytical reference standard with the molecular formula C8H10N2O4 and a molecular weight of 198.18 g/mol.
The molecular framework of 2-((2-Hydroxyethyl)amino)-5-nitrophenol2- (C8H10N2O4) 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).
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), 2-((2-Hydroxyethyl)amino)-5-nitrophenol2- 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.
