Dibenzo[b,i]phenazine CAS 258-76-4

Description

Compared with other compounds in its class, the molecular weight of 280.32 g/mol gives Dibenzo[b,i]phenazine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Dibenzo[b,i]phenazine (CAS 258-76-4), molecular formula C20H12N2 and molecular weight 280.32 g/mol, is a CATO reference standard with documented purity and traceability.

Dibenzo[b,i]phenazine (C20H12N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
