Compared with other compounds in its class, the molecular weight of 278.35 g/mol gives 2-Phenoxy-4-phenyl-5-propyl-1H-imidazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Phenoxy-4-phenyl-5-propyl-1H-imidazole (CAS 64792-48-9), molecular formula C18H18N2O and molecular weight 278.35 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Phenoxy-4-phenyl-5-propyl-1H-imidazole (C18H18N2O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
