5,7-Dichloro-2,3-dihydroimidazo[1,2-f]phenanthridine CAS 38040-83-4

Description

Compared with other compounds in its class, the molecular weight of 289.16 g/mol gives 5,7-Dichloro-2,3-dihydroimidazo[1,2-f]phenanthridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5,7-Dichloro-2,3-dihydroimidazo[1,2-f]phenanthridine (CAS 38040-83-4), molecular formula C15H10Cl2N2 and molecular weight 289.16 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 5,7-Dichloro-2,3-dihydroimidazo[1,2-f]phenanthridine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 289.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
