Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-(Trifluoromethyl)-4-(trimethylsilyl)-1H-pyrrolo[2,3-b]pyridine (CAS 1261365-59-6), molecular formula C11H21F3N2Si and molecular weight 266.38 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H21F3N2Si, 5-(Trifluoromethyl)-4-(trimethylsilyl)-1H-pyrrolo[2,3-b]pyridine contains fluorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 266.38 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.
