Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2-(1-(4-Chloropicolinoyl)-5-methoxy-2-methyl-1H-indol-3-yl)acetic acid (CAS 59823-61-9), a certified reference material (molecular formula C18H15ClN2O4, MW 358.78 g/mol) for analytical method development and quality control.
Based on its molecular formula C18H15ClN2O4, 2-(1-(4-Chloropicolinoyl)-5-methoxy-2-methyl-1H-indol-3-yl)acetic acid contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 358.78 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.
