5-Acetyl-1-(4-methylpiperazin-1-yl)-1,2,3,4-tetrahydropyrimidine-2,4-dione CAS 320420-08-4

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-1-(4-methylpiperazin-1-yl)-1,2,3,4-tetrahydropyrimidine-2,4-dione.

5-Acetyl-1-(4-methylpiperazin-1-yl)-1,2,3,4-tetrahydropyrimidine-2,4-dione (CAS 320420-08-4), molecular formula C11H16N4O3 and molecular weight 252.27 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 5-Acetyl-1-(4-methylpiperazin-1-yl)-1,2,3,4-tetrahydropyrimidine-2,4-dione (C11H16N4O3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 252.27 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
