Chemical Structure
Description
1-((4-Bromo-5-methoxy-2-methylphenyl)sulfonyl)-4-phenylpiperazine (C18H21BrN2O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
1-((4-Bromo-5-methoxy-2-methylphenyl)sulfonyl)-4-phenylpiperazine (CAS 898650-79-8) is a high-purity analytical reference standard with the molecular formula C18H21BrN2O3S and a molecular weight of 425.34 g/mol.
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.
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.
