Chemical Structure
Description
6-Bromo-2-oxo-1,2,3,4-tetrahydro-2lambda4-isoquinoline (CAS 147497-32-4) is a high-purity analytical reference standard with the molecular formula C9H9BrNO and a molecular weight of 227.08 g/mol.
6-Bromo-2-oxo-1,2,3,4-tetrahydro-2lambda4-isoquinoline (C9H9BrNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 6-Bromo-2-oxo-1,2,3,4-tetrahydro-2lambda4-isoquinoline 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.
