Niclosamide-¹³C₆

5-Chloro-N-(2-chloro-4-nitrophenyl-¹³C₆)-2-hydroxybenzamide

Niclosamide-13C6 (CAS 1325808-64-7) is a high-purity reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. This stable isotope labeled anthelmintic reference material supports reliable LC-MS/MS and GC-MS quantification, precise calibration, and full traceability. Consequently, you can perform method validation and confirmatory analysis with confidence across diverse matrices and workflows.

Developed for performance and routine use, this reference standard helps you build robust analytical methods from the start:

• Optimized for LC-MS/MS and GC-MS calibration and quantification.
• Traceability supported by a comprehensive Certificate of Analysis with lot-specific purity and identity data.
• Gravimetrically assigned content for accuracy and reproducibility.
• Streamlined confirmatory analysis and day-to-day quality control.

Choose it for demanding applications that require dependable results and defensible data. Moreover, WITEGA Laboratorien Berlin-Adlershof GmbH ensures consistent quality, enabling clear data interpretation and reduced rework.

Typical use cases include:

• Regulated laboratories conducting residue control and compliance testing.
• Pharmaceutical research focused on metabolism and biotransformation studies.
• Multi-residue method development in food, feed, and environmental matrices.
• Method validation, recovery experiments, and matrix-matched calibration.

Because it is isotope labeled, the reference standard mirrors the analyte during extraction and ionization. Therefore, it strengthens quantification and guards against matrix effects. Furthermore, Niclosamide-13C6 (CAS 1325808-64-7) enhances selectivity for MRM transitions and reduces ambiguity from coeluting components.

Practical guidance for routine workflows:

• Prepare calibration curves across the target range and verify linearity.
• Use for system suitability and ongoing performance checks.
• Apply in confirmatory analysis by monitoring labeled and native transitions.
• Maintain traceability by documenting batch, concentration, and purity from the CoA.

Select this reference standard from WITEGA Laboratorien Berlin-Adlershof GmbH to streamline LC-MS/MS and GC-MS workflows, improve method validation, and support consistent, defensible results.
