Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Ethyl 4-Hydroxy-7-methoxy-3-quinolinecarboxylate (CAS 63463-15-0), a certified reference material (molecular formula C13H13NO4, MW 247.25 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl 4-Hydroxy-7-methoxy-3-quinolinecarboxylate (C13H13NO4) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), Ethyl 4-Hydroxy-7-methoxy-3-quinolinecarboxylate 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.
