Chemical Structure

2-Acetylcyclopentane-1,3-dione CAS 3859-39-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 140.14 g/mol gives 2-Acetylcyclopentane-1,3-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Acetylcyclopentane-1,3-dione (CAS 3859-39-0) is a high-purity analytical reference standard with the molecular formula C7H8O3 and a molecular weight of 140.14 g/mol.

The molecular framework of 2-Acetylcyclopentane-1,3-dione (C7H8O3) 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 the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

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.
