tributyl(cyclopropylethynyl)stannane CAS 254108-69-5

Description

Compared with other compounds in its class, the molecular weight of 355.15 g/mol gives tributyl(cyclopropylethynyl)stannane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies tributyl(cyclopropylethynyl)stannane (CAS 254108-69-5), a certified reference material (molecular formula C17H32Sn, MW 355.15 g/mol) for analytical method development and quality control.

Owing to an organic framework, tributyl(cyclopropylethynyl)stannane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 355.15 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.

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.
