Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 175.14 g/mol gives 8-Nitrocinnoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
8-Nitrocinnoline (CAS 2942-37-2) is a high-purity analytical reference standard with the molecular formula C8H5N3O2 and a molecular weight of 175.14 g/mol.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 8-Nitrocinnoline is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 175.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 8-Nitrocinnoline 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.
