Compared with other compounds in its class, the molecular weight of 501.49 g/mol gives 16-Nitroanthra[9,1,2-cde]benzo[rst]pentaphene-5,10-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
16-Nitroanthra[9,1,2-cde]benzo[rst]pentaphene-5,10-dione (CAS 128-60-9), molecular formula C34H15NO4 and molecular weight 501.49 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 16-Nitroanthra[9,1,2-cde]benzo[rst]pentaphene-5,10-dione (C34H15NO4) is characterized by a nitrogen-containing heterocyclic scaffold, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
