Description

15(R)-hydroperoxy-EPE, also known as hepes, belongs to the class of organic compounds known as n-alkylpiperazines. These are organic compounds containing a piperazine ring where the nitrogen ring atom carries an alkyl group. It was first documented in 2008 (PMID: 17984079). Based on a literature review very few articles have been published on 15(R)-hydroperoxy-EPE (PMID: 22732654).
