Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Acetyl-3-(sec-butyl)-5-hydroxyimidazolidine-2,4-dione.
5-Acetyl-3-(sec-butyl)-5-hydroxyimidazolidine-2,4-dione (CAS 71239-22-0), molecular formula C9H14N2O4 and molecular weight 214.22 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C9H14N2O4, 5-Acetyl-3-(sec-butyl)-5-hydroxyimidazolidine-2,4-dione contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 214.22 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
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.
