Chemical Structure
Description
As a certified reference material (CRM), 4-[5-(chloromethyl)-1,2,4-oxadiazol-3-yl]pyridine hydrochloride 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.
4-[5-(chloromethyl)-1,2,4-oxadiazol-3-yl]pyridine hydrochloride (CAS 1311313-79-7), molecular formula C8H6ClN3OHCl and molecular weight 232.06 g/mol, is a CATO reference standard with documented purity and traceability.
4-[5-(chloromethyl)-1,2,4-oxadiazol-3-yl]pyridine hydrochloride (C8H6ClN3OHCl) 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; 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.
