Chemical Structure

[μ-[1,2-ethanediolato(2-)-κO:κO′]]tetrakis[1,2-ethanediolato(2-)-κO,κO′]di-Silicate dipotassium stereoisomer CAS 137704-77-9 chemical structure

Description

[μ-[1,2-ethanediolato(2-)-κO:κO′]]tetrakis[1,2-ethanediolato(2-)-κO,κO′]di-Silicate dipotassium stereoisomer (C10H20O10Si2K) contains a carbohydrate-derived structure. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

[μ-[1,2-ethanediolato(2-)-κO:κO′]]tetrakis[1,2-ethanediolato(2-)-κO,κO′]di-Silicate dipotassium stereoisomer (CAS 137704-77-9), molecular formula C10H20O10Si2K and molecular weight 395.53 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.
