Fenbufen-D₉

4-(Biphenyl-4-yl-D₉)-4-oxobutanoic acid

Fenbufen-D9 (CAS 1189940-96-2) is a high-purity reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. It supports LC-MS/MS and GC-MS quantification of fenbufen in plasma, serum, or environmental matrices. With stable isotope labeling, it mirrors native analyte behavior closely. Therefore, you achieve robust calibration and traceable results from the first injection.

This reference standard enables accurate calibration, method validation, and confirmatory analysis across regulated workflows. Each lot comes with documentation for identity and purity to support traceability. Analysts use it to verify extraction efficiency and to monitor instrument performance. Moreover, the compound helps reduce matrix effects and improves quantitation at low levels.

• Optimized for LC-MS/MS and GC-MS response matching
• Stable isotope labeling for reliable quantification
• Traceable documentation for audits and compliance
• Suitable for calibration curves and daily quality control
• Consistent lot-to-lot performance

Typical applications include:

• Regulated laboratories performing residue control
• Pharmaceutical research and development
• Metabolism and pharmacokinetic studies
• Multi-residue method development in complex matrices
• Confirmatory analysis in routine testing

Use this reference standard to build linear calibration curves and to confirm analyte identity by MRM or SIM. You can validate recovery, precision, and detection limits confidently. In addition, the material streamlines cross-lab harmonization through traceable data. Order Fenbufen-D9 (CAS 1189940-96-2) from WITEGA Laboratorien Berlin-Adlershof GmbH and equip your LC-MS/MS or GC-MS methods for consistent performance.
