Tris(t-butoxy)(2,2-dimethylpropylidyne)tungsten(VI) (CAS 78234-36-3), molecular formula C17H36O3W and molecular weight 472.31 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C17H36O3W, Tris(t-butoxy)(2,2-dimethylpropylidyne)tungsten(VI) contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 472.31 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
