Chemical Structure
Description
The occurrence of PSS-Octa(2-trichlorosilylethyl) substituted is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
PSS-Octa(2-trichlorosilylethyl) substituted (CAS 214675-88-4), molecular formula C16H32Cl24O12Si16 and molecular weight 1716.66 g/mol, is a CATO reference standard with documented purity and traceability.
PSS-Octa(2-trichlorosilylethyl) substituted (C16H32Cl24O12Si16) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
