Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 158.20 g/mol gives 2-Methyl-4-phenylimidazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Methyl-4-phenylimidazole (CAS 13739-48-5) is a high-purity analytical reference standard with the molecular formula C10H10N2 and a molecular weight of 158.20 g/mol.
The molecular framework of 2-Methyl-4-phenylimidazole (C10H10N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
