(2,4-dioxo-1,2,3,4-tetrahydropyrimidin-5-yl)boronic acid CAS 70523-22-7

Description

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.

(2,4-dioxo-1,2,3,4-tetrahydropyrimidin-5-yl)boronic acid (CAS 70523-22-7), molecular formula C4H7BN2O4 and molecular weight 157.92 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (2,4-dioxo-1,2,3,4-tetrahydropyrimidin-5-yl)boronic acid (C4H7BN2O4) is characterized by a carbohydrate-derived structure, an amide group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
