Fenpyrazone

4-[2-Chloro-4-(methylsulfonyl)-3-[(2,2,2-trifluoroethoxy)methyl]benzoyl]-1-ethyl-1H-pyrazol-5-yl 1,3-dimethyl-1H-pyrazole-4-carboxylate

Fenpyrazone (CAS 1992017-55-6) reference standard supports LC-MS/MS and GC-MS workflows for precise quantification. This material enables LC-MS/MS calibration. It also acts as a residue analysis reference for food, environmental, and research matrices. It is produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH, ensuring consistent quality and reliable supply. Use it to establish traceability, verify recovery, and confirm target analytes with confidence.

Develop robust calibration curves and define reporting limits with confidence. The reference standard helps you validate methods, assess matrix effects, and support confirmatory analysis. It improves traceability across batches and instruments. Moreover, it fits seamlessly into LC-MS/MS or GC-MS quantification protocols used in daily quality control.

Typical use cases include regulated laboratories, pharmaceutical research, residue control programs, metabolism studies, and multi-residue method development. Laboratories rely on this reference standard to calibrate instruments, benchmark recoveries, and verify identification criteria.

Key benefits:

• High-purity reference standard optimized for LC-MS/MS and GC-MS quantification.
• Supports calibration, method validation, and confirmatory analysis.
• Traceable preparation and clear lot labeling for audit-ready documentation.
• Suitable for multi-residue workflows and routine residue control.
• Consistent performance for complex matrices and diverse extraction protocols.

Practical guidance:

• Prepare an appropriate stock solution using a suitable solvent.
• Build multi-point calibration curves across the expected concentration range.
• Verify accuracy with independent QC levels and blank matrices.
• Apply instrument tuning to maintain sensitivity and selectivity.

Every batch of the Fenpyrazone (CAS 1992017-55-6) reference standard is supplied by WITEGA Laboratorien Berlin-Adlershof GmbH. Therefore, ordering and technical support remain straightforward and reliable for your projects.
