Chemical Structure
Description
1-(2-Chloro-5-(trifluoromethyl)phenyl)-2-methyl-5-(4-(methylsulfonyl)phenyl)-1H-pyrrole (CAS 338749-72-7) is a high-purity analytical reference standard with the molecular formula C19H15ClF3NO2S and a molecular weight of 413.84 g/mol.
Based on its molecular formula C19H15ClF3NO2S, 1-(2-Chloro-5-(trifluoromethyl)phenyl)-2-methyl-5-(4-(methylsulfonyl)phenyl)-1H-pyrrole contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 413.84 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.
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.
