2-[(3-{[1,1'-biphenyl]-4-yl}-1-phenyl-1H-pyrazol-4-yl)methylidene]-2,3-dihydro-1H-indene-1,3-dione CAS 956741-95-0 chemical structure

Description

The occurrence of 2-[(3-{[1,1'-biphenyl]-4-yl}-1-phenyl-1H-pyrazol-4-yl)methylidene]-2,3-dihydro-1H-indene-1,3-dione is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-[(3-{[1,1'-biphenyl]-4-yl}-1-phenyl-1H-pyrazol-4-yl)methylidene]-2,3-dihydro-1H-indene-1,3-dione (CAS 956741-95-0), molecular formula C31H20N2O2 and molecular weight 452.50 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, 2-[(3-{[1,1'-biphenyl]-4-yl}-1-phenyl-1H-pyrazol-4-yl)methylidene]-2,3-dihydro-1H-indene-1,3-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 452.50 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 2-[(3-{[1,1'-biphenyl]-4-yl}-1-phenyl-1H-pyrazol-4-yl)methylidene]-2,3-dihydro-1H-indene-1,3-dione 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.
