5-Acetyl-3,3-dimethyl-2,3-dihydro-1h-indol-2-one (CAS 855420-20-1), molecular formula C12H13NO2 and molecular weight 203.24 g/mol, is a CATO reference standard with documented purity and traceability.
5-Acetyl-3,3-dimethyl-2,3-dihydro-1h-indol-2-one (C12H13NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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.
