Diafenthiuron-urea

3-(2,6-Diisopropyl-4-phenoxyphenyl)-1-tert-butyl urea

Diafenthiuron-urea (CAS 136337-67-2) is a high-purity reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. It supports LC-MS/MS and GC-MS quantification from screening to confirmatory analysis. As a pesticide residue standard and an LC-MS/MS calibration solution, it helps you build reliable calibration curves and achieve traceable results for routine monitoring in regulated workflows.

Use this reference standard to validate extraction recovery, assess matrix effects, and confirm analyte identity using retention time and ion ratio criteria. It enables traceability across batches and instruments. Therefore, you can harmonize methods between sites and maintain compliance. Moreover, it fits seamlessly into multi-analyte workflows without compromising selectivity.

Typical application areas include:

• Regulated laboratories performing confirmation and reporting under quality systems
• Food and feed residue control programs with strict action limits
• Pharmaceutical research and metabolism studies targeting pesticide metabolites
• Environmental monitoring of transformation products in complex matrices
• Multi-residue method development with LC-MS/MS or GC-MS platforms

Analytical tasks supported by this reference standard:

• Calibration and bracketing for quantitative analysis
• System suitability checks and instrument performance trending
• Spike and recovery experiments for matrix validation
• LOD and LOQ verification with clear acceptance criteria
• Confirmatory analysis with traceable identifiers and documentation

Every unit is supplied by WITEGA Laboratorien Berlin-Adlershof GmbH with supporting documentation for identity and quality. Consequently, it integrates into quality-controlled workflows that demand robust traceability and reproducibility. Choose Diafenthiuron-urea to streamline calibration, ensure confident confirmatory analysis, and accelerate method validation across LC-MS/MS and GC-MS systems.
