Chemical Structure
Description
CATO supplies rac 5-(3-Pyridyl)tetrahydro-2-furanone (CAS 20971-79-3), a certified reference material (molecular formula C9H9NO2, MW 163.17 g/mol) for analytical method development and quality control.
The molecular framework of rac 5-(3-Pyridyl)tetrahydro-2-furanone (C9H9NO2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), rac 5-(3-Pyridyl)tetrahydro-2-furanone meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
