Chemical Structure
Description
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.
Disodium 2-hydrogen arsonatoacetate hydrate (CAS 6018-31-1) is a high-purity analytical reference standard with the molecular formula C2H3AsO5NaH2O and a molecular weight of 222.97 g/mol.
Disodium 2-hydrogen arsonatoacetate hydrate (C2H3AsO5NaH2O) contains a carboxylic acid 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 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.
