Chemical Structure
Description
Silver(I) 2-(1H-imidazol-1-yl)acetate (CAS 934965-86-3), molecular formula C5H5AgN2O2 and molecular weight 232.97 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Silver(I) 2-(1H-imidazol-1-yl)acetate (C5H5AgN2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 232.97 g/mol, it falls into the medium-molecular-weight range. 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.
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.
