Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
ethyl 2-(2-oxo-4-piperidyl)acetate (CAS 102943-18-0) is a high-purity analytical reference standard with the molecular formula C9H15NO3 and a molecular weight of 185.22 g/mol.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, ethyl 2-(2-oxo-4-piperidyl)acetate is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 185.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), ethyl 2-(2-oxo-4-piperidyl)acetate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
