1,2-Di(1-naphthyl)-1,2-ethanedione CAS 3457-41-8

Description

The occurrence of 1,2-Di(1-naphthyl)-1,2-ethanedione 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.

1,2-Di(1-naphthyl)-1,2-ethanedione (CAS 3457-41-8) is a high-purity analytical reference standard with the molecular formula C22H14O2 and a molecular weight of 310.35 g/mol.

Structurally, 1,2-Di(1-naphthyl)-1,2-ethanedione (C22H14O2) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 310.35 g/mol, it falls into the moderately-high-molecular-weight range. 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), 1,2-Di(1-naphthyl)-1,2-ethanedione 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.
