Chemical Structure

Sodium orthosilicate CAS 13472-30-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 184.04 g/mol gives Sodium orthosilicate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Sodium orthosilicate (CAS 13472-30-5), molecular formula Na2O4SiNa2 and molecular weight 184.04 g/mol, is a CATO reference standard with documented purity and traceability.

Sodium orthosilicate (Na2O4SiNa2) contains an inorganic composition. It is notably hygroscopic; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.
