Description

Compared with other compounds in its class, the molecular weight of 450.43 g/mol gives 1,1’’-[(1,1-Dimethylethyl)[[(1R,2E)-1-ethyl-3-iodo-2-propen-1-yl]oxy]silylene]bis-benzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1,1’’-[(1,1-Dimethylethyl)[[(1R,2E)-1-ethyl-3-iodo-2-propen-1-yl]oxy]silylene]bis-benzene (CAS 1309610-39-6) is a high-purity analytical reference standard with the molecular formula C21H27IOSi and a molecular weight of 450.43 g/mol.

Structurally, 1,1’’-[(1,1-Dimethylethyl)[[(1R,2E)-1-ethyl-3-iodo-2-propen-1-yl]oxy]silylene]bis-benzene (C21H27IOSi) contains a steroid core, a hydroxyl group, an ether linkage, iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 450.43 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

As a certified reference material (CRM), 1,1’’-[(1,1-Dimethylethyl)[[(1R,2E)-1-ethyl-3-iodo-2-propen-1-yl]oxy]silylene]bis-benzene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
