Chemical Structure
Description
The occurrence of Methyl 5-hydroxy-1-tosyl-1H-indole-3-carboxylate is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Methyl 5-hydroxy-1-tosyl-1H-indole-3-carboxylate (CAS 930112-00-8), molecular formula C17H15NO5S and molecular weight 345.37 g/mol, is a CATO reference standard with documented purity and traceability.
Methyl 5-hydroxy-1-tosyl-1H-indole-3-carboxylate (C17H15NO5S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
