O,O’-Dimethyl-O’’-(3-methyl-4-methylsulfonyl phenyl) thiophosphate

Fenthion sulfone (CAS 3761-42-0) reference standard supports LC-MS/MS and GC-MS quantification across residue and metabolism studies. This traceable analytical standard is produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH, ensuring consistent quality for calibration and confirmatory analysis. Use it to streamline method validation and achieve reliable reporting in regulated laboratories.

Built for routine and advanced workflows, it helps you:

• Establish robust calibration curves for quantitative assays.
• Verify instrument performance during LC-MS/MS or GC-MS runs.
• Demonstrate traceability and reproducible recovery.
• Confirm identity through retention time and qualifier transitions.

Analysts use this material in food and feed residue control, environmental monitoring, and agricultural matrices. It also supports pharmaceutical research on pesticide interactions and metabolism. Because it is a metabolite of fenthion, it fits multi-residue method development strategies. Therefore, it suits screening and targeted workflows alike.

Each lot includes documentation for identity, purity, and concentration, enabling clear audit trails. Prepare working solutions with suitable solvents and reach stable response factors. Then execute calibration, quality control, and confirmatory batches without delays.

• Applications: residue screening, targeted quantification, and confirmatory analysis.
• Matrices: food, feed, water, soil, and plant extracts.
• Techniques: LC-MS/MS and GC-MS for sensitive multi-residue programs.

WITEGA Laboratorien Berlin-Adlershof GmbH supplies this reference standard worldwide. Our team supports method transfer, stability guidance, and documentation requests. Choose this reference standard to improve sensitivity, selectivity, and data comparability across labs.
