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 Potassium 5-(hydroxymethyl)-2,6-dioxo-1,2,3,6-tetrahydropyrimidine-4-carboxylate.
Potassium 5-(hydroxymethyl)-2,6-dioxo-1,2,3,6-tetrahydropyrimidine-4-carboxylate (CAS 4156-76-7) is a high-purity analytical reference standard with the molecular formula C6H5N2O5K and a molecular weight of 224.21 g/mol.
Structurally, Potassium 5-(hydroxymethyl)-2,6-dioxo-1,2,3,6-tetrahydropyrimidine-4-carboxylate (C6H5N2O5K) contains a carbohydrate-derived structure, an amide group. The molecule exhibits a degree of unsaturation (DBE) of 5.5, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 224.21 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.
As a certified reference material (CRM), Potassium 5-(hydroxymethyl)-2,6-dioxo-1,2,3,6-tetrahydropyrimidine-4-carboxylate 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.
