Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 497.10 g/mol gives 1-Chloro-1,2,3,4,5-pentaphenyl-1H-silole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-Chloro-1,2,3,4,5-pentaphenyl-1H-silole (CAS 16030-07-2), molecular formula C34H25ClSi and molecular weight 497.10 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-Chloro-1,2,3,4,5-pentaphenyl-1H-silole (C34H25ClSi) contains chlorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 22.0, corresponding to approximately 22 ring(s) or double-bond equivalent(s). With a molecular weight of 497.10 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
