4-Dimethylamino-1,5-dimethyl-2-phenyl-1,2-dihydro-pyrazol-3-one

4 Dimethylaminoantipyrine Aminophenazone (CAS 58-15-1) is a high-purity reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. This analytical reference material for LC-MS/MS supports precise calibration and reliable GC-MS quantification across diverse matrices. Designed for traceable workflows, it helps build robust methods and defensible results.

Use this reference standard to establish calibration curves, verify linearity, and assess recovery. Laboratories also apply it to method validation, selectivity checks, and confirmatory analysis. Each lot comes with a certificate of analysis that documents purity, identity, and concentration. Consequently, you gain traceability and confidence in every result.

Typical applications include:

• Regulated laboratories needing verifiable calibration and quality control.
• Pharmaceutical research focused on metabolite profiling and pharmacokinetics.
• Residue control programs monitoring therapeutic compounds in complex samples.
• Metabolism studies requiring accurate quantification across time points.
• Multi-residue method development with LC-MS/MS or GC-MS platforms.

The material suits routine and advanced workflows. Prepare standards in suitable solvents to match your matrix. Store according to the certificate to preserve stability. Use in spike-and-recovery tests, matrix effects evaluation, and carryover checks. With the 4 Dimethylaminoantipyrine Aminophenazone (CAS 58-15-1) reference standard from WITEGA Laboratorien Berlin-Adlershof GmbH, you can streamline quantification and ensure reproducibility.

For batch-to-batch consistency, we provide lot traceability and documented handling recommendations. The reference standard supports instrument qualification, routine system suitability, and long-term method maintenance. As a result, regulated workflows remain defensible and efficient.
