Description
3-[(1Z)-1-[2-(6-Chloropyridin-2-yl)hydrazin-1-yl]-2-(1H-1,2,4-triazol-1-yl)ethylidene]-1-phenylurea (CAS 338418-61-4), molecular formula C16H15ClN8O and molecular weight 370.80 g/mol, is a CATO reference standard with documented purity and traceability.
3-[(1Z)-1-[2-(6-Chloropyridin-2-yl)hydrazin-1-yl]-2-(1H-1,2,4-triazol-1-yl)ethylidene]-1-phenylurea (C16H15ClN8O) 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.
As a certified reference material (CRM), 3-[(1Z)-1-[2-(6-Chloropyridin-2-yl)hydrazin-1-yl]-2-(1H-1,2,4-triazol-1-yl)ethylidene]-1-phenylurea 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.
