Description
CATO supplies 1024154-45-7 2-(3-bromophenyl)-1-(3,5-difluorophenyl)-6,6-dimethyl-4,5,6,7-tetrahydro-1H-indol-4-one MS-10297 (CAS 1024154-45-7), a certified reference material (molecular formula C22H18BrF2NO, MW 430.29 g/mol) for analytical method development and quality control.
Structurally, 1024154-45-7 2-(3-bromophenyl)-1-(3,5-difluorophenyl)-6,6-dimethyl-4,5,6,7-tetrahydro-1H-indol-4-one MS-10297 (C22H18BrF2NO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 430.29 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
