Description

Compared with other compounds in its class, the molecular weight of 292.12 g/mol gives 2-Chloro-5-[3-(2-chlorophenyl)-1,2,4-oxadiazol-5-yl]pyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Chloro-5-[3-(2-chlorophenyl)-1,2,4-oxadiazol-5-yl]pyridine (CAS 303144-86-7), molecular formula C13H7Cl2N3O and molecular weight 292.12 g/mol, is a CATO reference standard with documented purity and traceability.

2-Chloro-5-[3-(2-chlorophenyl)-1,2,4-oxadiazol-5-yl]pyridine (C13H7Cl2N3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 2-Chloro-5-[3-(2-chlorophenyl)-1,2,4-oxadiazol-5-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.
