4-Amino-N-(5-methoxy-6-methoxy-D₃-pyrimindin-4-yl)benzenesulfonamide

Sulfadoxine D3 (CAS 1262770-70-6) is a high-purity reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. This deuterated antibiotic reference standard supports LC-MS/MS and GC-MS calibration, traceability, and robust quantification in residue and metabolism studies. It enables confident method validation and confirmatory analysis in regulated laboratories and pharmaceutical research.

Designed for demanding workflows, it provides consistent isotopic labeling and a clear mass shift for selective detection. Additionally, each batch includes a detailed CoA to support documentation and audits.

• Optimized for LC-MS/MS and GC-MS calibration and system suitability.
• Traceable purity and identity verified by HPLC and qNMR.
• D3 mass shift simplifies discrimination from native matrices.
• Suitable for calibration curves, recovery checks, and confirmatory analysis.

Typical applications include:

• Residue control in food and environmental samples.
• Pharmaceutical research and metabolism studies.
• Regulated laboratory workflows and multi-residue method development.
• Verification of sample preparation and matrix effects.

Use Sulfadoxine D3 (CAS 1262770-70-6) to build linear, stable calibration models and verify traceability across batches. Store as recommended and prepare fresh dilutions when possible. Moreover, document lot numbers to streamline audits. Therefore, this reference standard helps tighten uncertainty budgets and improve decision limits across complex matrices.
