Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 247.29 g/mol gives Ethyl2-oxo-3-phenylpiperidine-3-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl2-oxo-3-phenylpiperidine-3-carboxylate (CAS 63378-71-2), molecular formula C14H17NO3 and molecular weight 247.29 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Ethyl2-oxo-3-phenylpiperidine-3-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 247.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
