Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2,3-Dihydrobenzo[g]quinolin-4(1H)-one (CAS 21516-07-4), molecular formula C13H11NO and molecular weight 197.23 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,3-Dihydrobenzo[g]quinolin-4(1H)-one (C13H11NO) 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).
As a certified reference material (CRM), 2,3-Dihydrobenzo[g]quinolin-4(1H)-one 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.
