4-(4-Chlorophenyl)-5-{2'-fluoro-4'-propyl-[1,1'-biphenyl]-4-yl}-1-(4-iodobenzoyl)-1H-pyrazole CAS 477762-85-9

Description

The occurrence of 4-(4-Chlorophenyl)-5-{2'-fluoro-4'-propyl-[1,1'-biphenyl]-4-yl}-1-(4-iodobenzoyl)-1H-pyrazole is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine/iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-(4-Chlorophenyl)-5-{2'-fluoro-4'-propyl-[1,1'-biphenyl]-4-yl}-1-(4-iodobenzoyl)-1H-pyrazole (CAS 477762-85-9), molecular formula C31H23ClFIN2O and molecular weight 620.88 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine/iodine substitution, 4-(4-Chlorophenyl)-5-{2'-fluoro-4'-propyl-[1,1'-biphenyl]-4-yl}-1-(4-iodobenzoyl)-1H-pyrazole is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 620.88 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), 4-(4-Chlorophenyl)-5-{2'-fluoro-4'-propyl-[1,1'-biphenyl]-4-yl}-1-(4-iodobenzoyl)-1H-pyrazole 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.
