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 3-(3-Methyl-1H-indol-1-yl)isobenzofuran-1(3H)-one (CAS 6308-56-1), a certified reference material (molecular formula C17H13NO2, MW 263.29 g/mol) for analytical method development and quality control.
Based on its molecular formula C17H13NO2, 3-(3-Methyl-1H-indol-1-yl)isobenzofuran-1(3H)-one contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 263.29 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.
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.
