Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-(Trimethylstannyl)-α-[[5-(trimethylstannyl)-2-thienyl]methylene]-2-thiopheneacetonitrile (CAS 1965250-77-4), molecular formula C17H23NS2Sn2 and molecular weight 542.92 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 5-(Trimethylstannyl)-α-[[5-(trimethylstannyl)-2-thienyl]methylene]-2-thiopheneacetonitrile is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 542.92 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).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
