Description
CATO supplies 3-(Trihydroxysilylpropyl)-1-propanesulphonic acid 3-(trihydroxysilyl)propane-1-sulfonic acid 70942-24-4 (CAS 70942-24-4), a certified reference material (molecular formula C3H10O6SSi, MW 202.26 g/mol) for analytical method development and quality control.
3-(Trihydroxysilylpropyl)-1-propanesulphonic acid 3-(trihydroxysilyl)propane-1-sulfonic acid 70942-24-4 (C3H10O6SSi) contains a sulfone group, a carboxylic acid 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.
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.
