Manganese(II) oxalate dihydrate (CAS 88682-90-0) is a high-purity analytical reference standard with the molecular formula C2O4MnH2O and a molecular weight of 160.97 g/mol.
Structurally, Manganese(II) oxalate dihydrate (C2O4MnH2O) contains a carboxylic acid group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 160.97 g/mol, it falls into the medium-molecular-weight range.
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.
