Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1H-indol-3-ol, 5-methoxy-, 3-acetate (CAS 1070994-17-0) is a high-purity analytical reference standard with the molecular formula C11H11NO3 and a molecular weight of 205.21 g/mol.
Based on its molecular formula C11H11NO3, 1H-indol-3-ol, 5-methoxy-, 3-acetate contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 205.21 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
