4-Hydroxy-3-iodo-5-nitro-benzonitrile-¹³C₆

Nitroxynil 13C6 (CAS 1325559-31-6) is a stable isotope labeled reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. It supports LC-MS/MS and GC-MS quantification, calibration, method validation, and confirmatory analysis. Because it mirrors the native analyte yet remains distinguishable by mass, it improves selectivity and confidence. Moreover, its traceability helps laboratories meet rigorous quality requirements and audit expectations.

This reference standard was developed for reliable calibration curves and accurate recovery assessment across diverse matrices. It enables robust workflows in residue monitoring and research. Additionally, it helps reduce matrix effects and enhances precision during routine screening or targeted quantification.

• High lot-to-lot consistency for dependable calibration and QC.
• Clear documentation for traceability and audit readiness.
• Optimized for LC-MS/MS and GC-MS workflows.
• Designed for calibration, method validation, and confirmatory analysis.
• Isotopic labeling that supports confident peak identification.

Typical use cases include regulated laboratories and accredited test houses. It also fits pharmaceutical research for biotransformation tracking and metabolite profiling. Furthermore, it supports residue control programs and metabolism studies in veterinary and food safety contexts. Teams working on multi-residue method development will value consistent performance and clear mass separation.

• Regulated laboratories performing targeted quantification.
• Pharmaceutical research and metabolism studies.
• Residue control in food and environmental samples.
• Development and validation of multi-residue methods.
• Confirmatory analysis to verify screening results.

During method development, use Nitroxynil 13C6 (CAS 1325559-31-6) to establish calibration ranges, evaluate linearity, and verify accuracy. Then apply it to routine QA and proficiency testing for ongoing traceability. In every case, the reference standard from WITEGA Laboratorien Berlin-Adlershof GmbH provides the reliability required to maintain data integrity and demonstrate compliance.
