Chemical Structure
Description
3-[4,5-bis(4-phenylphenyl)-1h-imidazol-2-yl]phenol (CAS 296792-52-4), molecular formula C33H24N2O and molecular weight 464.56 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-[4,5-bis(4-phenylphenyl)-1h-imidazol-2-yl]phenol (C33H24N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 23.0, corresponding to approximately 23 ring(s) or double-bond equivalent(s). With a molecular weight of 464.56 g/mol, it falls into the moderately-high-molecular-weight range. 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.
