Chemical Structure
Description
The occurrence of 3-Iodo-2-(pyrrolidin-1-yl)pyridine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Iodo-2-(pyrrolidin-1-yl)pyridine (CAS 1235440-37-5) is a high-purity analytical reference standard with the molecular formula C9H11IN2 and a molecular weight of 274.10 g/mol.
3-Iodo-2-(pyrrolidin-1-yl)pyridine (C9H11IN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 3-Iodo-2-(pyrrolidin-1-yl)pyridine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
