Description
Compared with other compounds in its class, the molecular weight of 217.26 g/mol gives 3-Isopropyl-2-methyl-1H-indole-5-carboxylic acid 5284AE 54233-21-5 C13H15NO2 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Isopropyl-2-methyl-1H-indole-5-carboxylic acid 5284AE 54233-21-5 C13H15NO2 (CAS 54233-21-5), molecular formula C13H15NO2 and molecular weight 217.26 g/mol, is a CATO reference standard with documented purity and traceability.
3-Isopropyl-2-methyl-1H-indole-5-carboxylic acid 5284AE 54233-21-5 C13H15NO2 (C13H15NO2) contains a nitrogen-containing heterocyclic scaffold, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
