Chemical Structure

Stannane, [3-(2-ethylhexyl)-2,5-thiophenediyl]bis[trimethyl- CAS 886746-70-9 chemical structure

Description

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.

Stannane, [3-(2-ethylhexyl)-2,5-thiophenediyl]bis[trimethyl- (CAS 886746-70-9), molecular formula C18H36SSn2 and molecular weight 521.96 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Stannane, [3-(2-ethylhexyl)-2,5-thiophenediyl]bis[trimethyl- (C18H36SSn2) contains sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 521.96 g/mol, it falls into the moderately-high-molecular-weight range. 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.
