Chemical Structure
Description
Trimethyl(tosylethynyl)silane (CAS 34452-56-7) is a high-purity analytical reference standard with the molecular formula C12H16O2SSi and a molecular weight of 252.40 g/mol.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Trimethyl(tosylethynyl)silane is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 252.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), Trimethyl(tosylethynyl)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.
