Chemical Structure
Description
The occurrence of Trichloro(cyclooctyl)silane is closely related to chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Trichloro(cyclooctyl)silane (CAS 18290-59-0), molecular formula C8H15Cl3Si and molecular weight 245.65 g/mol, is a CATO reference standard with documented purity and traceability.
Trichloro(cyclooctyl)silane (C8H15Cl3Si) contains chlorine substitution. Halogen substitution raises its density and boiling point; 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.
