Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 295.12 g/mol gives 4-Iodo-N-phenylaniline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Iodo-N-phenylaniline (CAS 74686-56-9), molecular formula C12H10IN and molecular weight 295.12 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-Iodo-N-phenylaniline (C12H10IN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 295.12 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
