Chemical Structure

6-(Piperazine-1-carbonyl)pyrimidine-2,4(1H,3H)-dione hydrochloride CAS 4318-57-4 chemical structure

Description

The occurrence of 6-(Piperazine-1-carbonyl)pyrimidine-2,4(1H,3H)-dione hydrochloride is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

6-(Piperazine-1-carbonyl)pyrimidine-2,4(1H,3H)-dione hydrochloride (CAS 4318-57-4) is a high-purity analytical reference standard with the molecular formula C9H12N4O3HCl and a molecular weight of 260.68 g/mol.

Structurally, 6-(Piperazine-1-carbonyl)pyrimidine-2,4(1H,3H)-dione hydrochloride (C9H12N4O3HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 260.68 g/mol, it falls into the medium-molecular-weight range. 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).

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.
