Chemical Structure
Description
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.
(S)-2-methyl-4-((2-(4-(trifluoromethyl)phenyl)-9H-carbazol-9-yl)methyl)-4,5-dihydrooxazole (CAS 2357080-11-4) is a high-purity analytical reference standard with the molecular formula C24H19F3N2O and a molecular weight of 408.42 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, (S)-2-methyl-4-((2-(4-(trifluoromethyl)phenyl)-9H-carbazol-9-yl)methyl)-4,5-dihydrooxazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 408.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
