α-(4-Chlorophenyl)-2,6-dichloro-4-(3,5-dioxo-4,5-dihydro-3H-1,2,4-triazin-2-yl)benzeneacetonitrile

Diclazuril (CAS 101831-37-2) is a high-purity reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. As a residue analysis reference material and LC-MS/MS calibration solution, it supports robust quantification in challenging food and feed matrices. Therefore, laboratories can implement consistent workflows and meet strict regulatory targets with confidence.

Designed for LC-MS/MS and GC-MS workflows, this reference standard enables accurate calibration, traceability, method validation, and confirmatory analysis. Moreover, its quality documentation streamlines audits and supports defensible data. Each batch is controlled to ensure reliable performance in quantitative assays.

Key advantages include:

• High purity for precise calibration across linear ranges.
• Comprehensive traceability and clear documentation for audits.
• Consistent lot performance to reduce revalidation work.
• Fit for LC-MS/MS and GC-MS quantification and confirmation.

Typical applications:

• Regulated laboratory quality control and proficiency testing.
• Pharmaceutical research exploring veterinary drug interactions.
• Residue control programs in food safety monitoring.
• Metabolism studies and pathway elucidation.
• Multi-residue method development and optimization.

Additionally, the material supports routine calibration curve construction, recovery studies, matrix-matched validation, and system suitability checks. It helps confirm target identity through ion ratio verification and retention time matching. Furthermore, it integrates smoothly into existing SOPs and harmonized methods.
