Chemical Structure
Description
9-Bromo-1,2,3,5,6,7-hexahydropyrido[3,2,1-ij]quinoline hydrobromide (CAS 70173-55-6), molecular formula C12H14BrNHBr and molecular weight 333.07 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 9-Bromo-1,2,3,5,6,7-hexahydropyrido[3,2,1-ij]quinoline hydrobromide (C12H14BrNHBr) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 333.07 g/mol, it falls into the moderately-high-molecular-weight range. 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), 9-Bromo-1,2,3,5,6,7-hexahydropyrido[3,2,1-ij]quinoline hydrobromide 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.
