3-(4-Bromophenyl)-1-p-tolyl-1H-pyrazol-4-ol CAS 1202030-45-2

Description

The occurrence of 3-(4-Bromophenyl)-1-p-tolyl-1H-pyrazol-4-ol is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-(4-Bromophenyl)-1-p-tolyl-1H-pyrazol-4-ol (CAS 1202030-45-2), molecular formula C16H13BrN2O and molecular weight 329.19 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C16H13BrN2O, 3-(4-Bromophenyl)-1-p-tolyl-1H-pyrazol-4-ol contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 329.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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-(4-Bromophenyl)-1-p-tolyl-1H-pyrazol-4-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.
