1-(4-Bromophenyl)-2-(4-nitro-1h-pyrazol-1-yl)ethan-1-one CAS 1240574-93-9

Description

The occurrence of 1-(4-Bromophenyl)-2-(4-nitro-1h-pyrazol-1-yl)ethan-1-one 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.

CATO supplies 1-(4-Bromophenyl)-2-(4-nitro-1h-pyrazol-1-yl)ethan-1-one (CAS 1240574-93-9), a certified reference material (molecular formula C11H8BrN3O3, MW 310.10 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution, 1-(4-Bromophenyl)-2-(4-nitro-1h-pyrazol-1-yl)ethan-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 310.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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-(4-Bromophenyl)-2-(4-nitro-1h-pyrazol-1-yl)ethan-1-one 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.
