Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 276.32 g/mol gives Calcium 3-(2,4-dihydroxy-3,3-dimethylbutanamido)propanoate hydrate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Calcium 3-(2,4-dihydroxy-3,3-dimethylbutanamido)propanoate hydrate (CAS 331748-07-3) is a high-purity analytical reference standard with the molecular formula C9H16NO5CaH2O and a molecular weight of 276.32 g/mol.
Calcium 3-(2,4-dihydroxy-3,3-dimethylbutanamido)propanoate hydrate (C9H16NO5CaH2O) contains an amino-acid-derived structure, an amide group, a hydroxyl 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. 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.
