Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(1-Ethyl-4-hydroxypiperidin-4-yl)-2-phenylacetic acid (CAS 5449-34-3) is a high-purity analytical reference standard with the molecular formula C15H21NO3 and a molecular weight of 263.33 g/mol.
Based on its molecular formula C15H21NO3, 2-(1-Ethyl-4-hydroxypiperidin-4-yl)-2-phenylacetic acid contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 263.33 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
