Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-Ethyl-2-(4-(4-propylcyclohexyl)phenyl)pyridine (CAS 312748-39-3) is a high-purity analytical reference standard with the molecular formula C22H29N and a molecular weight of 307.47 g/mol.
Based on its molecular formula C22H29N, 5-Ethyl-2-(4-(4-propylcyclohexyl)phenyl)pyridine contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 307.47 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
