Chemical Structure

2-(2-Benzimidazolylamino)-6-methylpyrimidin-4(3H)-one CAS 42389-40-2 chemical structure

Description

2-(2-Benzimidazolylamino)-6-methylpyrimidin-4(3H)-one (CAS 42389-40-2), molecular formula C12H11N5O and molecular weight 241.25 g/mol, is a CATO reference standard with documented purity and traceability.

2-(2-Benzimidazolylamino)-6-methylpyrimidin-4(3H)-one (C12H11N5O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
