The occurrence of (E)-Acetaldehyde O-(2-methyl-1H-indol-3-yl) oxime is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(E)-Acetaldehyde O-(2-methyl-1H-indol-3-yl) oxime (CAS 89969-74-4) is a high-purity analytical reference standard with the molecular formula C11H12N2O and a molecular weight of 188.23 g/mol.
Based on its molecular formula C11H12N2O, (E)-Acetaldehyde O-(2-methyl-1H-indol-3-yl) oxime contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 188.23 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.
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.
