1-{1-[2-chloro-5-(trifluoromethyl)phenyl]-5-(4-methanesulfonylphenyl)-2-methyl-1H-pyrrol-3-yl}-2,2,2-trifluoroethan-1-one CAS 338749-77-2

Description

Based on its molecular formula C21H14ClF6NO3S, 1-{1-[2-chloro-5-(trifluoromethyl)phenyl]-5-(4-methanesulfonylphenyl)-2-methyl-1H-pyrrol-3-yl}-2,2,2-trifluoroethan-1-one 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 509.85 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.

1-{1-[2-chloro-5-(trifluoromethyl)phenyl]-5-(4-methanesulfonylphenyl)-2-methyl-1H-pyrrol-3-yl}-2,2,2-trifluoroethan-1-one (CAS 338749-77-2), molecular formula C21H14ClF6NO3S and molecular weight 509.85 g/mol, is a CATO reference standard with documented purity and traceability.

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.
