Pyrimethamin-D₃

5-(4-Chlorophenyl)-6-(ethyl-2,2,2-D₃)-2,4-pyrimidinediamine

Pyrimethamin-D3 (CAS 1189936-99-9) is a high-purity reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. Use it for LC-MS/MS and GC-MS quantification, traceability, calibration, method validation, and confirmatory analysis. As a deuterated antimalarial reference standard, it streamlines isotope dilution workflows. It also serves as a stable isotope labeled standard for LC-MS/MS. It supports a quantitative method validation standard for routine residue control. For advanced needs, rely on confirmatory analysis certified material and multi-residue method development.

Engineered for reproducible results, this material helps you build robust calibration models and achieve defensible data. You can integrate it into existing methods with minimal effort. Moreover, it offers strong traceability for regulated projects.

• Optimized for LC-MS/MS and GC-MS workflows to secure accurate quantification.
• Traceable purity with documented characterization to support audit-ready records.
• Consistent isotopic labeling for reliable response factors across batches.
• Suitable for calibration curves, matrix-matched spikes, and system suitability checks.
• Supports confirmatory analysis in complex matrices.

Typical applications include:

• Regulated laboratories requiring traceable reference materials.
• Pharmaceutical research targeting antimalarial metabolism and disposition.
• Residue control programs monitoring targeted analytes in food or environmental samples.
• Metabolism studies that demand stable isotope match and clean mass transitions.
• Multi-residue method development where selectivity and robustness matter.

Pyrimethamin-D3 (CAS 1189936-99-9) gives you confidence during calibration and verification. Additionally, it supports method transfer across instruments and sites. Therefore, your team can confirm results faster, reduce rework, and document performance with clarity.
