Chemical Structure

Tert-butyl((1R,2S)-2-ethynylcyclopropoxy)dimethylsilane CAS 155223-35-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 196.36 g/mol gives Tert-butyl((1R,2S)-2-ethynylcyclopropoxy)dimethylsilane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Tert-butyl((1R,2S)-2-ethynylcyclopropoxy)dimethylsilane (CAS 155223-35-1), molecular formula C11H20OSi and molecular weight 196.36 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Tert-butyl((1R,2S)-2-ethynylcyclopropoxy)dimethylsilane (C11H20OSi) contains a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 196.36 g/mol, it falls into the medium-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.

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.
