2-[[5-acetamido-4-[(2,4-dinitrophenyl)diazenyl]-2-ethoxy-phenyl]-(2-acetyloxyethyl)amino]ethyl ethanoate 375-16-6 A823715 acetic acid 2-[5-acetamido-N-(2-acetyloxyethyl)-4-(2,4-dinitrophenyl)azo-2-ethoxyanilino]ethyl ester (CAS 375-16-6) is a high-purity analytical reference standard with the molecular formula C4ClF7O and a molecular weight of 232.48 g/mol.

The molecular framework of 2-[[5-acetamido-4-[(2,4-dinitrophenyl)diazenyl]-2-ethoxy-phenyl]-(2-acetyloxyethyl)amino]ethyl ethanoate 375-16-6 A823715 acetic acid 2-[5-acetamido-N-(2-acetyloxyethyl)-4-(2,4-dinitrophenyl)azo-2-ethoxyanilino]ethyl ester (C4ClF7O) is characterized by a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
