Sulfadimidine-D4 Sulfamethazine-D4 (CAS 1020719-82-7) is a deuterium-labeled reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. It supports LC-MS/MS and GC-MS workflows for calibration, traceability, method validation, and confirmatory analysis in complex matrices. It aligns with these search intents: sulfonamide reference standard, stable isotope labeled standard, LC-MS/MS calibration, GC-MS quantification, residue analysis, traceability standard. Further contexts include: method validation, confirmatory analysis, regulated laboratories, pharmaceutical research, metabolism studies, multi-residue method development.

This Sulfadimidine-D4 Sulfamethazine-D4 reference standard integrates smoothly with established sample preparation protocols. Analysts can build reliable calibration curves, evaluate matrix effects, and verify recoveries with confidence. Lot-specific documentation enables traceable reporting and supports audits. Robust stability and convenient handling help maintain accuracy from preparation to injection.

• Optimized for LC-MS/MS and GC-MS quantification and calibration.
• Traceable purity supported by batch documentation and clear labeling.
• Effective for residue control in food, feed, and environmental samples.
• Supports pharmaceutical research and metabolism investigations.
• Enables defensible multi-residue method development and confirmation.

Use this reference standard to strengthen confirmatory analysis and reduce false positives in regulated workflows. In residue control, it helps confirm targeted sulfonamide signals across diverse matrices. In pharmaceutical research and metabolism studies, it aids pathway elucidation and cross-matrix comparisons. For multi-residue screening, it improves identification criteria and calibration robustness. For expert support and orders, contact WITEGA Laboratorien Berlin-Adlershof GmbH.
