2-Methyl-3,5-dinitrobenzamide-¹⁵N₃

Zoalene 15N3 is an isotopically labeled reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. It supports LC-MS/MS and GC-MS workflows for reliable quantification and traceability. As a dinitolmide isotope labeled reference material, it enables robust calibration for feed and tissue matrices. Laboratories also apply it as a coccidiostat reference standard in residue control. Furthermore, it serves as an LC MS MS calibration standard in confirmatory analysis.

Use this reference standard to build traceable calibration curves, validate methods, and confirm identities with MS/MS transitions. The 15N3 label enhances selectivity and reduces matrix effects. Therefore, you can improve accuracy across complex matrices. Zoalene 15N3 helps align your results with regulatory expectations and SOPs.

Key advantages for LC-MS/MS or GC-MS workflows include:

• High consistency and batch-to-batch comparability for reliable quantification.
• Clear documentation supporting traceability and data integrity.
• Compatibility with common solvents for flexible preparation.
• Utility in calibration, recovery checks, and system suitability.
• Robust performance for confirmatory analysis and revalidation.

Typical applications span diverse laboratories:

• Regulated laboratories performing routine residue control.
• Pharmaceutical research investigating metabolism and fate.
• Metabolism studies using isotope-labeled analytes in model systems.
• Multi-residue method development across feed, tissue, and environmental samples.
• Quality control units monitoring calibration and measurement uncertainty.

Integrate Zoalene 15N3 into LC-MS/MS or GC-MS methods to tighten quantification and enhance traceability. Prepare calibration levels that bracket your expected ranges. Additionally, verify matrix effects and recovery during method validation. Finally, apply the reference standard for routine checks to maintain long-term confidence in results.
