Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 290.98 g/mol gives Trimethyl(naphthalen-2-yl)stannane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Trimethyl(naphthalen-2-yl)stannane (CAS 945-77-7), molecular formula C13H16Sn and molecular weight 290.98 g/mol, is a CATO reference standard with documented purity and traceability.
Trimethyl(naphthalen-2-yl)stannane (C13H16Sn) contains an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
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.
