Chemical Structure

Anthraquinone-2-carboxylic Acid CAS 117-78-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 252.22 g/mol gives Anthraquinone-2-carboxylic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Anthraquinone-2-carboxylic Acid (CAS 117-78-2) is a high-purity analytical reference standard with the molecular formula C15H8O4 and a molecular weight of 252.22 g/mol.

Based on its molecular formula C15H8O4, Anthraquinone-2-carboxylic Acid contains a flavonoid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 252.22 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

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), Anthraquinone-2-carboxylic 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.
