Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(7-Butyl-6,8-dioxo-2,3,4,6,7,8-hexahydro-1H-pyrimido[1,6-a]pyrimidin-9-yl)benzamide.
N-(7-Butyl-6,8-dioxo-2,3,4,6,7,8-hexahydro-1H-pyrimido[1,6-a]pyrimidin-9-yl)benzamide (CAS 524944-74-9), molecular formula C18H22N4O3 and molecular weight 342.39 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, N-(7-Butyl-6,8-dioxo-2,3,4,6,7,8-hexahydro-1H-pyrimido[1,6-a]pyrimidin-9-yl)benzamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 342.39 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).
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.
As a certified reference material (CRM), N-(7-Butyl-6,8-dioxo-2,3,4,6,7,8-hexahydro-1H-pyrimido[1,6-a]pyrimidin-9-yl)benzamide 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.
