Chemical Structure
Description
1-(4-Bromophenyl)-2-methyl-5-phenyl-1H-pyrrole (CAS 26165-82-2), molecular formula C17H14BrN and molecular weight 312.20 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-(4-Bromophenyl)-2-methyl-5-phenyl-1H-pyrrole (C17H14BrN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 312.20 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
