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.
2-((((Z)-1-(2-Aminothiazol-4-yl)-2-(((2S,3S)-2-((carbamoyloxy)methyl)-4-oxo-1-sulfoazetidin-3-yl)amino)-2-oxoethylidene)amino)oxy)acetic acid (CAS 87638-04-8), molecular formula C12H14N6O10S2 and molecular weight 466.40 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-((((Z)-1-(2-Aminothiazol-4-yl)-2-(((2S,3S)-2-((carbamoyloxy)methyl)-4-oxo-1-sulfoazetidin-3-yl)amino)-2-oxoethylidene)amino)oxy)acetic acid (C12H14N6O10S2) is characterized by a carbohydrate-derived structure, an amide group, a sulfone group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
