5-(3-(2-Fluorophenyl)-1,2,4-oxadiazol-5-yl)pyridin-2-ol CAS 1239843-29-8

Description

As a certified reference material (CRM), 5-(3-(2-Fluorophenyl)-1,2,4-oxadiazol-5-yl)pyridin-2-ol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

5-(3-(2-Fluorophenyl)-1,2,4-oxadiazol-5-yl)pyridin-2-ol (CAS 1239843-29-8), molecular formula C13H8FN3O2 and molecular weight 257.22 g/mol, is a CATO reference standard with documented purity and traceability.

5-(3-(2-Fluorophenyl)-1,2,4-oxadiazol-5-yl)pyridin-2-ol (C13H8FN3O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
