Chemical Structure
Description
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.
Hydroxy-PEG3-MS (CAS 139115-89-2), molecular formula C7H16O6S and molecular weight 228.26 g/mol, is a CATO reference standard with documented purity and traceability.
Hydroxy-PEG3-MS (C7H16O6S) contains a carbohydrate-derived structure, a sulfone group. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.
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.
