Sodium 7,10-bis(carboxylatomethyl)-3,3-dimethoxy-2-oxa-7,10-diaza-3-siladodecan-12-oate CAS 128850-89-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 416.43 g/mol gives Sodium 7,10-bis(carboxylatomethyl)-3,3-dimethoxy-2-oxa-7,10-diaza-3-siladodecan-12-oate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Sodium 7,10-bis(carboxylatomethyl)-3,3-dimethoxy-2-oxa-7,10-diaza-3-siladodecan-12-oate (CAS 128850-89-5) is a high-purity analytical reference standard with the molecular formula C14H25N2O9SiNa and a molecular weight of 416.43 g/mol.

Structurally, Sodium 7,10-bis(carboxylatomethyl)-3,3-dimethoxy-2-oxa-7,10-diaza-3-siladodecan-12-oate (C14H25N2O9SiNa) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 416.43 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).

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.
