Chemical Structure
Description
The molecular framework of (9H-fluoren-9-yl)methyl 2-hydroxy-2-(piperidin-2-yl)acetate (C21H23NO3) is characterized by a steroid core, 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).
(9H-fluoren-9-yl)methyl 2-hydroxy-2-(piperidin-2-yl)acetate (CAS 170867-95-5), molecular formula C21H23NO3 and molecular weight 337.41 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.
