4-Hydroxy-3-iodo-5-nitro-benzonitrile

Nitroxynil (CAS 1689-89-0) reference standard supports precise LC-MS/MS calibration and GC-MS quantification for veterinary anthelmintic residue analysis. Produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH, it enables traceable workflows from calibration to confirmatory analysis and routine quality control. Laboratories rely on this material to establish reliable measurement results and consistent method performance.

This reference standard is manufactured with stringent quality controls and full documentation. Each batch is supported by a detailed certificate of analysis to demonstrate identity, purity, and assay values, ensuring traceability across your analytical lifecycle. Use it to prepare calibration curves, verify linearity, set reporting limits, and check specificity in quantitative LC-MS/MS or GC-MS assays. Because it is a robust reference standard, analysts can streamline validation and reduce rework.

• High chemical purity suitable for quantitative methods
• Traceable documentation for audits and compliance needs
• Optimized for LC-MS/MS and GC-MS workflows
• Ideal for calibration, method validation, and confirmatory analysis

Typical applications include regulated laboratories, pharmaceutical research, residue control, metabolism studies, and multi-residue method development. Use the Nitroxynil (CAS 1689-89-0) reference standard to benchmark system suitability, verify recovery, and confirm identity in complex matrices. Moreover, it helps standardize inter-lab comparisons and long-term trend monitoring.

• Residue and screening methods in food and feed monitoring
• Pharmacokinetic and metabolism investigations
• Targeted and multi-residue workflows
• Confirmatory testing with traceable reference levels

For best results, document all preparation steps and use appropriate solvents and glassware. Establish stability-indicating checks as part of your routine QC. Additionally, store according to best laboratory practice and your method requirements.

Order confidently from WITEGA Laboratorien Berlin-Adlershof GmbH. Our team provides batch-specific documentation and technical support to help integrate this reference standard into your LC-MS/MS or GC-MS calibration, validation, and confirmatory analysis workflows.
