Chemical Structure
Description
The molecular framework of 4,6,7-Trimethoxy-2,3-dihydrofuro[2,3-b]quinoline (C14H15NO4) 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 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).
4,6,7-Trimethoxy-2,3-dihydrofuro[2,3-b]quinoline (CAS 61402-58-2), molecular formula C14H15NO4 and molecular weight 261.27 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.
As a certified reference material (CRM), 4,6,7-Trimethoxy-2,3-dihydrofuro[2,3-b]quinoline 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.
