2-Chloro-4-(pyrrolidin-3-yl)pyridine (CAS 1260666-92-9), molecular formula C9H11ClN2 and molecular weight 182.65 g/mol, is a CATO reference standard with documented purity and traceability.
2-Chloro-4-(pyrrolidin-3-yl)pyridine (C9H11ClN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2-Chloro-4-(pyrrolidin-3-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.
