Chemical Structure
Description
Methyl 1-tosyl-1H-pyrrolo[2,3-b]pyridine-3-carboxylate (C16H14N2O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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).
Methyl 1-tosyl-1H-pyrrolo[2,3-b]pyridine-3-carboxylate (CAS 952182-23-9) is a high-purity analytical reference standard with the molecular formula C16H14N2O4S and a molecular weight of 330.36 g/mol.
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.
