1-[3-(4-Chlorophenyl)-1H-pyrazol-4-yl]-1H-1,2,4-triazole CAS 303996-63-6 chemical structure

Description

The occurrence of 1-[3-(4-Chlorophenyl)-1H-pyrazol-4-yl]-1H-1,2,4-triazole is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1-[3-(4-Chlorophenyl)-1H-pyrazol-4-yl]-1H-1,2,4-triazole (CAS 303996-63-6), a certified reference material (molecular formula C11H8ClN5, MW 245.67 g/mol) for analytical method development and quality control.

1-[3-(4-Chlorophenyl)-1H-pyrazol-4-yl]-1H-1,2,4-triazole (C11H8ClN5) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, 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), 1-[3-(4-Chlorophenyl)-1H-pyrazol-4-yl]-1H-1,2,4-triazole 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.
