Chemical Structure
Description
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, (1,3-Bis(methoxymethyl)-2,4-dioxo-1,2,3,4-tetrahydropyrimidin-5-yl)boronic acid is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 244.01 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
(1,3-Bis(methoxymethyl)-2,4-dioxo-1,2,3,4-tetrahydropyrimidin-5-yl)boronic acid (CAS 1256346-16-3), molecular formula C8H13BN2O6 and molecular weight 244.01 g/mol, is a CATO reference standard with documented purity and traceability.
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.
