Chemical Structure
Description
As a certified reference material (CRM), 6-bromo-2-oxo-1,2,3,4-tetrahydroquinoline-4-carboxylic acid 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.
6-bromo-2-oxo-1,2,3,4-tetrahydroquinoline-4-carboxylic acid (CAS 264276-41-7), molecular formula C10H8BrNO3 and molecular weight 270.08 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-bromo-2-oxo-1,2,3,4-tetrahydroquinoline-4-carboxylic acid (C10H8BrNO3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
