Chemical Structure
Description
Structurally, Carbonic acid, magnesium salt (CO3Mg) contains an organic framework. 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 84.31 g/mol, it falls into the low-molecular-weight range.
Carbonic acid, magnesium salt (CAS 7757-69-9), molecular formula CO3Mg and molecular weight 84.31 g/mol, is a CATO reference standard with documented purity and traceability.
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.
