Flubendazole-D₃

[5-(4-Fluorobenzoyl)-1H-benzimidazol-2-yl] carbamic acid methyl-D3 ester

Flubendazole-D3 (CAS 1173021-08-3) is a high-purity reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. It supports LC-MS/MS calibration solution preparation and serves as a GC-MS quantification reference for routine workflows. Use it as method validation control material and as a traceable analytical material for regulated laboratory QA QC. Analysts also apply it in multi-residue screening standard protocols, confirmatory analysis reference procedures, and pharmaceutical metabolism studies. The deuterated benzimidazole standard enables veterinary anthelmintic residue analysis with high confidence.

Develop robust quantification methods with this stable, isotopically labeled material. Its deuteration delivers consistent mass shifts and clean chromatographic behavior. As a result, you obtain precise calibration curves in LC-MS/MS and GC-MS. You also maintain traceability across batches and reduce matrix effects during confirmatory analysis.

Typical applications include:

• Calibration and system suitability for residue control programs
• Method validation parameters such as linearity, accuracy, precision, and LOQ or LOD
• Routine QC checks in regulated laboratories and proficiency testing
• Metabolism and pharmacokinetic research in pharmaceutical studies
• Multi-residue method development with harmonized retention and MRM transitions

Each reference standard from WITEGA Laboratorien Berlin-Adlershof GmbH includes comprehensive documentation to support traceability and audits. Prepare calibration levels and quality controls with your preferred solvent and follow established protocols. Store under recommended conditions to preserve integrity. With Flubendazole-D3 (CAS 1173021-08-3), you strengthen data comparability and meet strict reporting requirements for LC-MS/MS and GC-MS workflows.
