Compared with other compounds in its class, the molecular weight of 189.25 g/mol gives 1-Ethyl-2-methylindoline-5-carbaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-Ethyl-2-methylindoline-5-carbaldehyde (CAS 887690-40-6), molecular formula C12H15NO and molecular weight 189.25 g/mol, is a CATO reference standard with documented purity and traceability.
1-Ethyl-2-methylindoline-5-carbaldehyde (C12H15NO) 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; 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.
