2-((7-Chloro-4-nitrobenzo[c][1,2,5]oxadiazol-5-yl)amino)ethan-1-ol CAS 378201-55-9

Description

2-((7-Chloro-4-nitrobenzo[c][1,2,5]oxadiazol-5-yl)amino)ethan-1-ol (CAS 378201-55-9) is a high-purity analytical reference standard with the molecular formula C8H7ClN4O4 and a molecular weight of 258.62 g/mol.

The molecular framework of 2-((7-Chloro-4-nitrobenzo[c][1,2,5]oxadiazol-5-yl)amino)ethan-1-ol (C8H7ClN4O4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
