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).
