General description

Cyclopentanone is a cyclic ketone that occurs in allium species, beef, cheese, and chicken. It is generally used as a fragrance ingredient in fragrances and in non-cosmetic products.

Application


  • High-oxygen-modified atmospheric packaging delays flavor and quality deterioration in fresh-cut broccoli.: This research investigates the impact of high-oxygen-modified atmospheric packaging on the preservation of fresh-cut broccoli. Cyclopentanone is identified as a significant compound in the aroma profile, contributing to the understanding of packaging technologies that maintain food quality and extend shelf life. (He et al., 2024).

  • Selective production of methylindan and tetralin with xylose or hemicellulose.: The study focuses on the selective production of methylindan and tetralin using xylose or hemicellulose, with Cyclopentanone playing a key role in the catalytic processes. This research provides insights into sustainable chemical production from biomass-derived feedstocks. (Zou et al., 2024).

  • Synthesis of Hydroxylamine via Ketone-Mediated Nitrate Electroreduction.: This paper presents a novel method for synthesizing hydroxylamine through ketone-mediated nitrate electroreduction, utilizing Cyclopentanone. The findings demonstrate the versatility of Cyclopentanone in electrochemical synthesis and its potential for green chemistry applications. (Jia et al., 2024).

In plants, oxylipins regulate developmental processes and defense responses. The first specific step in the biosynthesis of the cyclopentanone class of oxylipins is catalyzed by allene oxide cyclase (AOC) that forms cis(+)-12-oxo-phytodienoic acid. The moss Physcomitrella patens has two AOCs
