Rifaximin

Rifaximin (CAS 80621-81-4) reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH enables confident LC-MS/MS and GC-MS quantification. This antibiotic reference standard supports LC-MS/MS calibration and robust target confirmation. It delivers consistent response factors and reliable retention time matching. Therefore, you gain accuracy across batches from the start.

Designed for routine and advanced workflows, the material ensures full traceability from synthesis to certificate. Use it for calibration curves, instrument tuning, and spike recovery experiments. It streamlines method validation and confirmatory analysis under demanding regulatory expectations. Moreover, the clean profile reduces matrix interferences. You benefit from stable and reproducible results every run.

• LC-MS/MS calibration and system suitability checks
• GC-MS validation and selectivity assessment
• Method validation, accuracy, precision, and linearity studies
• Confirmatory analysis in targeted assays
• Traceable quantification for routine quality control

Typical applications include:
