Chemical Structure
Description
The occurrence of [9,9'-Bianthracene]-10-carbaldehyde is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
[9,9'-Bianthracene]-10-carbaldehyde (CAS 77802-21-2) is a high-purity analytical reference standard with the molecular formula C29H18O and a molecular weight of 382.45 g/mol.
[9,9'-Bianthracene]-10-carbaldehyde (C29H18O) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), [9,9'-Bianthracene]-10-carbaldehyde 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.
