Description
CATO manufactures Triethyl(p-tolyl)silane 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.
Triethyl(p-tolyl)silane (CAS 3644-91-5), molecular formula C13H22Si and molecular weight 206.40 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an organic framework, Triethyl(p-tolyl)silane is typically white to off-white low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 206.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
