Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Chloro(1H-inden-2-yl)dimethylsilane (CAS 240823-57-8) is a high-purity analytical reference standard with the molecular formula C11H13ClSi and a molecular weight of 208.76 g/mol.
Based on its molecular formula C11H13ClSi, Chloro(1H-inden-2-yl)dimethylsilane contains chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 208.76 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
