Chemical Structure

[9,9'-Bifluorenylidene]-2,2',7,7'-tetrayltetraboronic acid CAS 1220840-63-0 chemical structure

Description

The occurrence of [9,9'-Bifluorenylidene]-2,2',7,7'-tetrayltetraboronic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

[9,9'-Bifluorenylidene]-2,2',7,7'-tetrayltetraboronic acid (CAS 1220840-63-0), molecular formula C26H20B4O8 and molecular weight 503.68 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, [9,9'-Bifluorenylidene]-2,2',7,7'-tetrayltetraboronic acid (C26H20B4O8) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 17.0, corresponding to approximately 17 ring(s) or double-bond equivalent(s). With a molecular weight of 503.68 g/mol, it falls into the moderately-high-molecular-weight range. 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), [9,9'-Bifluorenylidene]-2,2',7,7'-tetrayltetraboronic acid 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.
