4-Acetamidoantipyrine

N-(1,5-Dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl)acetamide

4-Acetamidoantipyrine (CAS 83-15-8) is a high-purity reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. Laboratories use this material as an analytical reference material for LC-MS/MS and GC-MS. It supports traceability, calibration, and accurate quantification. Therefore, it helps establish reliable response factors and robust identification. This reference standard meets the needs of routine testing and advanced research.

Use it to calibrate instruments, validate methods, and perform confirmatory analysis. Each batch includes lot-specific data and a Certificate of Analysis for transparency and traceability. The material enables linear calibration ranges and low limits of detection in LC-MS/MS or GC-MS workflows. Moreover, it supports matrix-matched calibration and recovery checks. Consequently, it strengthens data integrity across studies.

Typical applications include:

• Regulated laboratories requiring defensible, traceable measurement results
• Pharmaceutical research and metabolite profiling
• Residue control and surveillance programs
• Metabolism studies in preclinical or environmental contexts
• Multi-residue method development and verification

Recommended use in analytical workflows:

1. Prepare a gravimetrically verified stock solution.
2. Generate multi-level calibration solutions.
3. Assess linearity, precision, and recovery.
4. Run confirmatory analysis with independent criteria.
5. Document lot, expiration, and storage conditions.

The reference standard ships with clear labeling and handling guidance. Store it under recommended conditions to preserve stability. Additionally, WITEGA Laboratorien Berlin-Adlershof GmbH provides technical support for implementation. 4-Acetamidoantipyrine (CAS 83-15-8) enables consistent calibration across platforms. Choose it for dependable LC-MS/MS and GC-MS quantification.
