2-(1-Naphthylmethylene)-1H-indene-1,3(2H)-dione CAS 25116-35-2

Description

The occurrence of 2-(1-Naphthylmethylene)-1H-indene-1,3(2H)-dione 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.

2-(1-Naphthylmethylene)-1H-indene-1,3(2H)-dione (CAS 25116-35-2) is a high-purity analytical reference standard with the molecular formula C20H12O2 and a molecular weight of 284.31 g/mol.

Structurally, 2-(1-Naphthylmethylene)-1H-indene-1,3(2H)-dione (C20H12O2) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 284.31 g/mol, it falls into the medium-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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
