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.
CATO supplies (S)-1-(3,6-Dibromo-9H-carbazol-9-yl)-3-((3-methoxyphenyl)amino)propan-2-ol (CAS 1235481-43-2), a certified reference material (molecular formula C22H20Br2N2O2, MW 504.21 g/mol) for analytical method development and quality control.
(S)-1-(3,6-Dibromo-9H-carbazol-9-yl)-3-((3-methoxyphenyl)amino)propan-2-ol (C22H20Br2N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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).
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.
