Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 415.98 g/mol gives Trichloro(icosyl)silane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Trichloro(icosyl)silane (CAS 18733-57-8) is a high-purity analytical reference standard with the molecular formula C20H41Cl3Si and a molecular weight of 415.98 g/mol.
Owing to chlorine substitution, Trichloro(icosyl)silane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 415.98 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), Trichloro(icosyl)silane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
