Chloromethiuron

N-(4-Chloro-2-methyl-phenyl)-N’,N’-dimethyl thiourea

Chloromethiuron (CAS 28217-97-2) reference standard from WITEGA Laboratorien Berlin-Adlershof GmbH supports LC-MS/MS and GC-MS quantification for residue testing workflows. As a precise pesticide residue standard, it enables traceable calibration and strong method validation from screening through confirmatory analysis. Laboratories implement it easily, achieve stable retention behavior, and gain reproducible response factors for reliable results.

Produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH, this material fits routine QA needs. You can build calibration curves, check linearity, and verify ion ratios without guesswork. Moreover, you can confirm analyte identity by monitoring qualifier and quantifier transitions in LC-MS/MS or characteristic ions in GC-MS. Consequently, you improve traceability and reduce uncertainty across batches and instruments.

• Calibration for quantitative LC-MS/MS or GC-MS assays
• Method validation: accuracy, precision, recovery, and LOQ
• System suitability and carryover checks
• Confirmatory analysis with ion ratio criteria
• Ongoing quality control and trend monitoring

Analysts in regulated laboratories, pharmaceutical research groups, residue control programs, and academic teams trust this reference standard to streamline workflows. It also supports metabolism studies and multi-residue method development, where selectivity and robustness matter. In addition, the material integrates into routine SOPs and complements matrix-matched calibration where required.

• Regulatory monitoring and proficiency testing
• Pharmaceutical discovery support and DMPK interfaces
• Food, feed, and environmental residue control
• Metabolism and degradation pathway research
• High-throughput multi-residue screening

Choose WITEGA Laboratorien Berlin-Adlershof GmbH for dependable documentation and consistent lot continuity. Chloromethiuron (CAS 28217-97-2) reference standard helps you maintain defensible data, improve comparability between instruments, and simplify audits. With clear traceability, your team can concentrate on decisions rather than troubleshooting.
