Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(1,3-Dibutyl-2,5-dioxoimidazolidin-4-ylidene)benzamide.
N-(1,3-Dibutyl-2,5-dioxoimidazolidin-4-ylidene)benzamide (CAS 88192-05-6), molecular formula C18H23N3O3 and molecular weight 329.39 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-(1,3-Dibutyl-2,5-dioxoimidazolidin-4-ylidene)benzamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 329.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), N-(1,3-Dibutyl-2,5-dioxoimidazolidin-4-ylidene)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.
