N-(5-Iodo-2,4-dioxo-3,4-dihydropyrimidin-1(2H)-yl)acetamide CAS 138481-93-3 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.

CATO supplies N-(5-Iodo-2,4-dioxo-3,4-dihydropyrimidin-1(2H)-yl)acetamide (CAS 138481-93-3), a certified reference material (molecular formula C6H6IN3O3, MW 295.03 g/mol) for analytical method development and quality control.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system, N-(5-Iodo-2,4-dioxo-3,4-dihydropyrimidin-1(2H)-yl)acetamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 295.03 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).

As a certified reference material (CRM), N-(5-Iodo-2,4-dioxo-3,4-dihydropyrimidin-1(2H)-yl)acetamide 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.
