4-Formylaminoantipyrine-D3 FAA-D3 is a deuterated reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. It fits LC-MS/MS and GC-MS workflows for precise quantification. Use it as a stable isotope labeled standard to support LC-MS/MS calibration, as a traceable analytical reference, and for residue control testing. It also serves pharmaceutical research standard needs and multi-residue method development. Consequently, analysts gain accuracy, robustness, and repeatability across diverse matrices.

This reference standard strengthens calibration, method validation, and confirmatory analysis. You can build traceability from neat material to working solutions. Its consistent isotopic labeling and purity help reduce matrix effects and improve detection limits. Therefore, calibration curves stay reliable, day after day.

• Supports LC-MS/MS and GC-MS quantification with excellent lot-to-lot consistency.
• Enhances traceability from preparation to routine analysis.
• Improves calibration linearity and signal interpretation.
• Enables confident confirmatory analysis in complex samples.

Typical applications include regulated laboratories, residue control, metabolism studies, and pharmaceutical research. It fits multi-residue method development, from screening to targeted quantification. Moreover, it integrates smoothly into existing SOPs and QA systems, saving time during validation.

• Method validation: accuracy, precision, recovery, and stability studies.
• Calibration: prepare matrix-matched or solvent-based curves.
• Quality control: routine checks for retention time, response, and transitions.
• Confirmatory analysis: verify identity and concentration with selective MRM or SIM.

Choose this reference standard from WITEGA Laboratorien Berlin-Adlershof GmbH to achieve reliable results and maintain defensible data in modern mass spectrometry laboratories.
