2-Cyano acetic acid-2-[(1,4-dioxido-2-quinoxalinyl-¹³C₆)methylene]hydrazide

Cyadox 13C6 is a premium reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. As an isotopically labeled reference standard, it supports precise LC-MS/MS and GC-MS analytical quantification, robust calibration, and full traceability. Laboratories choose it to build reliable methods, minimize matrix effects, and deliver confident confirmatory analysis. This material helps you reach low limits of quantification while keeping data integrity under control.

Use this reference standard to prepare calibration curves, verify recovery, and assess selectivity. The 13C6 labeling ensures co-elution with the native analyte and comparable ionization, which improves accuracy. Furthermore, its consistent purity and clearly defined concentration aid method validation and day-to-day quality control. Detailed documentation, including lot-specific information and storage guidance, strengthens traceability from sample preparation to final report.

• Regulated testing laboratories: routine residue monitoring and proficiency testing.
• Pharmaceutical research: metabolism studies and metabolite tracking across matrices.
• Residue control programs: screening and confirmatory analysis with stable, traceable calibration.
• Method development: multi-residue workflows requiring reliable identification and quantification.
• Validation tasks: precision, accuracy, linearity, and robustness checks.

Additionally, the Cyadox 13C6 reference standard supports verification of carryover and ion suppression during LC-MS/MS or GC-MS runs. It helps you optimize extraction and cleanup steps, choose effective calibration ranges, and cross-check instrument performance over time. Therefore, you can streamline workflows and reduce reanalysis. For availability, technical support, and documentation, please contact WITEGA Laboratorien Berlin-Adlershof GmbH. Deploy Cyadox 13C6 in your next validation or confirmatory campaign to ensure reproducible, defensible, and traceable results.
