Description
3-Amino-8-((2-amino-1,6-dimethylpyrimidin-4(1H)-ylidene)amino)-6-(4-aminophenyl)-5-methylphenanthridin-5-ium bromide hydrobromide (CAS 14222-46-9), molecular formula C26H26N7HBrBr and molecular weight 597.36 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-Amino-8-((2-amino-1,6-dimethylpyrimidin-4(1H)-ylidene)amino)-6-(4-aminophenyl)-5-methylphenanthridin-5-ium bromide hydrobromide (C26H26N7HBrBr) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 597.36 g/mol, it falls into the moderately-high-molecular-weight range. 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.
