Oxyphenbutazone

4-Butyl-1-(4-hydroxyphenyl)-2-phenylpyrazolidine-3,5-dione

Oxyphenbutazone (CAS 129-20-4) reference standard, produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH, supports LC-MS/MS and GC-MS quantification from sample preparation to final readout. As a traceable analytical reference material, it streamlines calibration, method validation, and confirmatory analysis in demanding workflows. Regulated laboratories benefit from its consistency. Researchers also use it for residue control, metabolism studies, and multi-residue method development.

This reference standard offers reliable lot-to-lot performance and clear documentation for traceability. It helps build robust calibration curves and reduces uncertainty in complex matrices. Furthermore, it aligns with stringent quality requirements for pharmaceutical research and monitoring programs.

Key advantages include:

• High purity for precise LC-MS/MS and GC-MS quantification
• Traceable production, shipped with complete documentation
• Optimized for calibration, method validation, and confirmatory analysis
• Suitable for residue control and metabolism investigations
• Compatible with multi-residue method development

Typical applications:

• Compliance testing in regulated laboratories
• Pharmaceutical and biomedical research
• Residue surveillance in complex matrices
• Metabolism and biotransformation studies
• Targeted and non-targeted screening workflows

Every batch of the Oxyphenbutazone (CAS 129-20-4) reference standard from WITEGA Laboratorien Berlin-Adlershof GmbH is manufactured under stringent quality controls to ensure accuracy and reproducibility. Use it to verify retention times, confirm identity with MS/MS transitions, and establish robust reporting limits. In short, this material supports confident quantification and defensible results across LC-MS/MS and GC-MS platforms.
