4-Amino-N-(4,6-dimethylpyrimidin-2-yl)benzenesulfonamide

Sulfadimidine Sulfamethazine (CAS 57-68-1) is a certified reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. Designed for LC-MS/MS calibration and GC-MS workflows, this sulfonamide reference standard supports traceable analytical quantification. As a LC-MS/MS calibration standard and a traceable analytical reference material, it enables robust method development from screening to confirmatory analysis in regulated environments.

With high purity and documented identity, Sulfadimidine Sulfamethazine (CAS 57-68-1) delivers reproducible responses across complex matrices. Use it to build calibration curves, verify linearity, and assess accuracy, precision, and recovery. It supports LC-MS/MS and GC-MS detection; therefore, it fits residue programs and metabolism studies. Comprehensive documentation facilitates traceability and defensible results for audits and routine monitoring.

Typical applications include:

• Regulated laboratories requiring traceable calibration and confirmatory analysis
• Pharmaceutical research and development for robust quantification
• Residue control in food and feed testing
• Metabolism studies and kinetic profiling
• Multi-residue method development and verification

Prepare stock solutions gravimetrically, then create matrix-matched calibration levels for sensitivity and selectivity. Furthermore, routine system suitability and ongoing calibration verification benefit from this reference standard. The material performs reliably as a bracketing calibrator, a quality control check, and a spike for recovery experiments. Consequently, laboratories achieve consistent calibration transfer between LC-MS/MS and GC-MS platforms.

Each batch of this reference standard comes from WITEGA Laboratorien Berlin-Adlershof GmbH with detailed documentation to support method validation, traceability, and reproducibility. Choose Sulfadimidine Sulfamethazine (CAS 57-68-1) to strengthen confidence in quantitative data from development through routine residue monitoring.
