1-(6-chloropyridazin-3-yl)-4-(1H-1,2,4-triazol-1-yl)-1H-pyrazol-5-ol CAS 1007038-60-9 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.

CATO supplies 1-(6-chloropyridazin-3-yl)-4-(1H-1,2,4-triazol-1-yl)-1H-pyrazol-5-ol (CAS 1007038-60-9), a certified reference material (molecular formula C9H6ClN7O, MW 263.64 g/mol) for analytical method development and quality control.

1-(6-chloropyridazin-3-yl)-4-(1H-1,2,4-triazol-1-yl)-1H-pyrazol-5-ol (C9H6ClN7O) 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.

As a certified reference material (CRM), 1-(6-chloropyridazin-3-yl)-4-(1H-1,2,4-triazol-1-yl)-1H-pyrazol-5-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.
