Sulfaquinoxaline

4-Amino-N-quinoxalin-2-yl-benzenesulfonamide

Sulfaquinoxaline (CAS 59-40-5) is a high-purity reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. It supports robust LC-MS/MS and GC-MS workflows for precise quantification and confident confirmation. As a sulfonamide residue analysis standard, an LC-MS/MS calibration standard for residues, and a GC-MS confirmatory analysis standard, it enables reliable data across matrices. Furthermore, its consistent quality helps you build linear calibration curves, assess matrix effects, and verify ion ratios with ease.

Designed for modern analytical demands, this reference standard strengthens traceability and day-to-day reproducibility. Use it to prepare calibration levels, QC samples, and system suitability checks. Moreover, it fits seamlessly into compliance-driven testing and in-depth research.

• Quantitative calibration for LC-MS/MS, with matrix-matched curves and stable response.
• Traceable characterization with a lot-specific Certificate of Analysis for confident reporting.
• Method validation support, including recovery, linearity, precision, selectivity, and LOD/LOQ.
• Confirmatory analysis with defined transitions and ion ratio verification in tandem MS.
• Compatibility with GC-MS workflows where applicable, from screening to confirmation.

Typical use cases span many sectors where dependable results matter:

• Regulated laboratories conducting official residue control and compliance testing.
• Pharmaceutical research focusing on sulfonamide characterization and profiling.
• Residue control programs evaluating veterinary drug carryover and depletion.
• Metabolism studies investigating transformation pathways and kinetics.
• Multi-residue method development across complex food and environmental matrices.

Each batch of this reference standard from WITEGA Laboratorien Berlin-Adlershof GmbH is released with detailed purity and identity data to ensure traceability. Additionally, storage guidance and safety documentation help maintain integrity from receipt to routine use. As a result, your calibration, validation, and confirmatory workflows remain consistent and defensible.
