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 Ethylenediaminetetraacetic acid disodium magnesium salt tetrahydrate.
Ethylenediaminetetraacetic acid disodium magnesium salt tetrahydrate (CAS 29932-54-5) is a high-purity analytical reference standard with the molecular formula C10H12MgN2O8NaH2O and a molecular weight of 353.52 g/mol.
Structurally, Ethylenediaminetetraacetic acid disodium magnesium salt tetrahydrate (C10H12MgN2O8NaH2O) contains a carbohydrate-derived structure, an amide group. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 353.52 g/mol, it falls into the moderately-high-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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
