Chemical Structure
Description
(3-Chlorophenyl)trimethylsilane (CAS 4405-42-9) is a high-purity analytical reference standard with the molecular formula C9H13ClSi and a molecular weight of 184.74 g/mol.
(3-Chlorophenyl)trimethylsilane (C9H13ClSi) 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.
CATO manufactures (3-Chlorophenyl)trimethylsilane under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
