5-(Phenylsulfanyl-1H-benzimidazol-2-yl)carbamic acid methyl ester

Fenbendazole (CAS 43210-67-9) reference standard from WITEGA Laboratorien Berlin-Adlershof GmbH enables precise LC-MS/MS and GC-MS quantification across demanding workflows. This anthelmintic reference standard supports traceable calibration in residue control and pharmaceutical research. As a benzimidazole veterinary drug standard, it fits multi-residue method development in regulated laboratories and delivers reproducible results from screening through confirmatory analysis.

Use this reference standard to build calibration curves with confidence and to verify instrument performance. Each batch supports traceability, method validation, and confirmatory analysis, so you meet compliance requirements. Furthermore, it integrates well into metabolism studies and stability investigations. With clear documentation and consistent quality, Fenbendazole (CAS 43210-67-9) helps maintain robust QC across projects.

Main analytical roles include:

• LC-MS/MS quantification with linear, matrix-matched calibration.
• GC-MS confirmation of identity via retention time and ion ratio checks.
• Traceability for residue analysis and inter-lab comparability.
• Method validation, including accuracy, precision, and recovery studies.

Typical use cases:

• Regulated laboratories verifying compliance for veterinary drug residues.
• Pharmaceutical research supporting development and metabolism studies.
• Residue control programs and surveillance testing.
• Multi-residue method development and routine confirmatory analysis.

Produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH, this reference standard streamlines setup and ongoing QC. It helps reduce rework, improves traceability, and strengthens documentation. Choose Fenbendazole (CAS 43210-67-9) to standardize calibration strategies, simplify validation, and ensure confident decision-making throughout LC-MS/MS and GC-MS pipelines.
