Sulfamonomethoxine-¹³C₆

4-Amino-N-(6-methoxy-pyrimidin-4-yl)-benzene-¹³C₆-sulfonamide

Sulfamonomethoxine-13C6 (CAS 1416768-32-5) is a stable isotope labeled sulfonamide reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. It supports confident LC-MS/MS and GC-MS quantification from the first injection. Use it to establish traceability, calibrate instruments, and verify specificity with clear confirmation criteria. The material delivers robust performance for targeted assays and multi-residue workflows.

This reference standard enables accurate calibration, method validation, and confirmatory analysis. Build linear calibration curves with minimal matrix effects. Strengthen traceability across batches and instruments. Moreover, apply it to spike-recovery studies and to verify retention time and isotope pattern fidelity. Because it is precisely characterized, your results stay comparable over time and across sites.

• High-purity reference standard for LC-MS/MS and GC-MS.
• Reliable calibration and ongoing system suitability checks.
• Strong support for traceability and confirmatory analysis.
• Optimized for method validation and ruggedness testing.
• Documented identity and content for defensible data.

Typical applications span regulated laboratories and research environments. Analysts in residue control, pharmaceutical metabolism studies, and environmental monitoring benefit from its consistent signal response. Developers of multi-residue methods can fine-tune transitions and optimize collision energies with confidence.

• Regulated laboratories performing routine residue control.
• Pharmaceutical research and metabolism studies.
• Food and feed surveillance programs.
• Environmental monitoring projects.
• Multi-residue method development and verification.

Every batch from WITEGA Laboratorien Berlin-Adlershof GmbH undergoes rigorous characterization to support traceable quantification. Use Sulfamonomethoxine-13C6 (CAS 1416768-32-5) to prepare stock and working solutions, establish multi-level calibration, and perform confirmation based on ion ratios. Consequently, you improve comparability, reduce uncertainty, and document method performance with clarity.
