Description
CATO manufactures Methyl 5-((trimethylsilyl)ethynyl)furan-2-carboxylate 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.
Methyl 5-((trimethylsilyl)ethynyl)furan-2-carboxylate (CAS 2435579-14-7) is a high-purity analytical reference standard with the molecular formula C11H14O3Si and a molecular weight of 222.31 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Methyl 5-((trimethylsilyl)ethynyl)furan-2-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 222.31 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.
