25102-12-9 421KAV3DHT Edetate dipotassium [USAN] Glycine, N,N'-1,2-ethanediylbis(N-(carboxymethyl))-dipotassium salt, dihydrate Edetate dipotassium Dipotassium dihydrogen (ethylenedinitrilo)tetraacetate, dihydrate Glycine, N,N'-1,2-ethanediylbis(N-(carboxymethyl)-, dipotassium salt, dihydrate UNII-421KAV3DHT (C10H14N2O8KH2O) contains a carbohydrate-derived structure, an amide group. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
