Description
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.
1-(3-Chloro-5-(trifluoromethyl)pyridin-2-yl)-N-(3-(5-(trifluoromethyl)pyridin-2-yl)phenyl)-1H-pyrrole-2-sulfonamide (CAS 1092346-21-8) is a high-purity analytical reference standard with the molecular formula C22H13ClF6N4O2S and a molecular weight of 546.87 g/mol.
Structurally, 1-(3-Chloro-5-(trifluoromethyl)pyridin-2-yl)-N-(3-(5-(trifluoromethyl)pyridin-2-yl)phenyl)-1H-pyrrole-2-sulfonamide (C22H13ClF6N4O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 546.87 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
