Chemical Structure
Description
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.
2-Chloro-4-[3-(propan-2-yl)-1,2,4-oxadiazol-5-yl]aniline (CAS 1343684-87-6), molecular formula C11H12ClN3O and molecular weight 237.69 g/mol, is a CATO reference standard with documented purity and traceability.
2-Chloro-4-[3-(propan-2-yl)-1,2,4-oxadiazol-5-yl]aniline (C11H12ClN3O) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 2-Chloro-4-[3-(propan-2-yl)-1,2,4-oxadiazol-5-yl]aniline 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.
