Chemical Structure

5-Hydroxy-2-piperidone CAS 19365-07-2 chemical structure

Description

As a certified reference material (CRM), 5-Hydroxy-2-piperidone 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.

5-Hydroxy-2-piperidone (CAS 19365-07-2), molecular formula C5H9NO2 and molecular weight 115.13 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-Hydroxy-2-piperidone (C5H9NO2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
