Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (Z)-Ethyl 2-(((2,5-dioxoimidazolidin-4-ylidene)methyl)amino)acetate.
(Z)-Ethyl 2-(((2,5-dioxoimidazolidin-4-ylidene)methyl)amino)acetate (CAS 258521-63-0), molecular formula C8H11N3O4 and molecular weight 213.19 g/mol, is a CATO reference standard with documented purity and traceability.
(Z)-Ethyl 2-(((2,5-dioxoimidazolidin-4-ylidene)methyl)amino)acetate (C8H11N3O4) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; 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.
