4-(5-Methyl-D₃-3-phenyl-isoxazol-4-yl)-N-propionyl-benzenesulfonamide

Parecoxib D3 is a deuterated reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. It supports LC-MS/MS and GC-MS quantification with high reliability, and it enables traceable analytical calibration for routine workflows. As a deuterated reference standard, it fits method validation and confirmatory analysis in regulated environments from the start.

This reference standard helps analysts build robust calibration curves, verify recoveries, and confirm identity with accurate mass or MRM transitions. Clearly documented lot traceability and consistent composition aid reproducibility across instruments and sites. Moreover, it integrates smoothly into multi-analyte methods and complex matrices.

• Optimized for LC-MS/MS and GC-MS quantification and calibration.
• Supports traceability for routine and investigational studies.
• Enables precise method validation, including accuracy and precision checks.
• Facilitates confirmatory analysis with stable isotopic labeling.
• Suitable for screening through confirmatory workflows and proficiency testing.

Typical applications cover a wide range of analytical tasks. Laboratories can apply it to high-throughput projects as well as targeted assays without changing established processes.

• Regulated laboratories requiring traceable calibration and documentation.
• Pharmaceutical research focused on development pipelines and bioanalytical studies.
• Residue control programs ensuring compliance and data defensibility.
• Metabolism studies that demand reliable quantification across time points.
• Multi-residue method development where selectivity and robustness matter.

For best results, prepare appropriate stock and working solutions, verify linear ranges, and monitor system suitability. Additionally, use matrix-matched calibration when needed and document recovery experiments. When you need consistent quality and dependable supply, rely on WITEGA Laboratorien Berlin-Adlershof GmbH to deliver this reference standard with the specifications your workflow requires.
