Chemical Structure
Description
Based on its molecular formula C17H15BrF2N2O, 6-Bromo-5-(2,4-difluorophenoxy)-1-isobutyl-1H-indazole contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 381.21 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.
6-Bromo-5-(2,4-difluorophenoxy)-1-isobutyl-1H-indazole (CAS 765914-75-8), molecular formula C17H15BrF2N2O and molecular weight 381.21 g/mol, is a CATO reference standard with documented purity and traceability.
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.
