1-Tosyl-1H-pyrrolo[2,3-b]pyridine-2-carbaldehyde CAS 479553-03-2

Description

The occurrence of 1-Tosyl-1H-pyrrolo[2,3-b]pyridine-2-carbaldehyde is closely related to a nitrogen-containing heterocyclic scaffold, 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.

1-Tosyl-1H-pyrrolo[2,3-b]pyridine-2-carbaldehyde (CAS 479553-03-2), molecular formula C15H12N2O3S and molecular weight 300.33 g/mol, is a CATO reference standard with documented purity and traceability.

1-Tosyl-1H-pyrrolo[2,3-b]pyridine-2-carbaldehyde (C15H12N2O3S) contains a nitrogen-containing heterocyclic scaffold, 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).

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.
