Chemical Structure
Description
6-Nitro-2-(piperazin-1-yl)quinoline maleate (C13H14N4O2C4H4O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; 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).
6-Nitro-2-(piperazin-1-yl)quinoline maleate (CAS 129047-05-8), molecular formula C13H14N4O2C4H4O4 and molecular weight 374.35 g/mol, is a CATO reference standard with documented purity and traceability.
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-Nitro-2-(piperazin-1-yl)quinoline maleate 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.
