Chemical Structure
Description
Tris(4-chlorophenyl)(hexadecyl)silane (CAS 18759-07-4), molecular formula C34H45Cl3Si and molecular weight 588.17 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C34H45Cl3Si, Tris(4-chlorophenyl)(hexadecyl)silane contains chlorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 588.17 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
