Chemical Structure
Description
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.
2-(2-Acetamido-6-oxo-1,6-dihydropyrimidin-4-yl)acetic acid (CAS 6943-71-1), molecular formula C17H14BrNO5 and molecular weight 392.20 g/mol, is a CATO reference standard with documented purity and traceability.
2-(2-Acetamido-6-oxo-1,6-dihydropyrimidin-4-yl)acetic acid (C17H14BrNO5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), 2-(2-Acetamido-6-oxo-1,6-dihydropyrimidin-4-yl)acetic acid 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.
