4-Chloro-1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridine CAS 744209-63-0

Description

The occurrence of 4-Chloro-1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridine is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Chloro-1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridine (CAS 744209-63-0), molecular formula C13H9ClN2O2S and molecular weight 292.74 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C13H9ClN2O2S, 4-Chloro-1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridine contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 292.74 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
