2,2-Dihydroxy-1H-phenalene-1,3(2H)-dione CAS 18931-20-9

Description

Compared with other compounds in its class, the molecular weight of 228.20 g/mol gives 2,2-Dihydroxy-1H-phenalene-1,3(2H)-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2,2-Dihydroxy-1H-phenalene-1,3(2H)-dione (CAS 18931-20-9), molecular formula C13H8O4 and molecular weight 228.20 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2,2-Dihydroxy-1H-phenalene-1,3(2H)-dione (C13H8O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), 2,2-Dihydroxy-1H-phenalene-1,3(2H)-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.
