Chemical Structure
Description
(5-Bromothiophen-2-yl)tributylstannane (CAS 143724-36-1) is a high-purity analytical reference standard with the molecular formula C16H29BrSSn and a molecular weight of 452.08 g/mol.
Owing to sulfur-containing functionality, bromine substitution, (5-Bromothiophen-2-yl)tributylstannane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 452.08 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.
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.
