Chemical Structure
Description
As a certified reference material (CRM), 5-Hydroxy-3-methyl-2-oxoimidazolidine-1-carboxamide 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-3-methyl-2-oxoimidazolidine-1-carboxamide (CAS 162830-39-9) is a high-purity analytical reference standard with the molecular formula C5H9N3O3 and a molecular weight of 159.14 g/mol.
The molecular framework of 5-Hydroxy-3-methyl-2-oxoimidazolidine-1-carboxamide (C5H9N3O3) 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.
