2-Chloro-4-(pyrrolidine-1-sulfonyl)pyridine CAS 1179655-82-3

Description

The occurrence of 2-Chloro-4-(pyrrolidine-1-sulfonyl)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.

CATO supplies 2-Chloro-4-(pyrrolidine-1-sulfonyl)pyridine (CAS 1179655-82-3), a certified reference material (molecular formula C9H11ClN2O2S, MW 246.71 g/mol) for analytical method development and quality control.

Structurally, 2-Chloro-4-(pyrrolidine-1-sulfonyl)pyridine (C9H11ClN2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 246.71 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
