Di(9H-fluoren-9-yl)dimethylsilane CAS 18769-00-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 388.58 g/mol gives Di(9H-fluoren-9-yl)dimethylsilane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Di(9H-fluoren-9-yl)dimethylsilane (CAS 18769-00-1), a certified reference material (molecular formula C28H24Si, MW 388.58 g/mol) for analytical method development and quality control.

Structurally, Di(9H-fluoren-9-yl)dimethylsilane (C28H24Si) contains a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 17.0, corresponding to approximately 17 ring(s) or double-bond equivalent(s). With a molecular weight of 388.58 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
