Chemical Structure
Description
The molecular framework of 5-(2-Cyclopentylethyl)-3-methylisoxazole (C11H17NO) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).
5-(2-Cyclopentylethyl)-3-methylisoxazole (CAS 921588-34-3), molecular formula C11H17NO and molecular weight 179.26 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
