Chemical Structure
Description
The occurrence of Methyl 1-(phenylsulfonyl)-1H-indole-2-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 1-(phenylsulfonyl)-1H-indole-2-carboxylate (CAS 60376-48-9), molecular formula C16H13NO4S and molecular weight 315.34 g/mol, is a CATO reference standard with documented purity and traceability.
Methyl 1-(phenylsulfonyl)-1H-indole-2-carboxylate (C16H13NO4S) 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.
