Chlorthiophos-sulfone

O-(2,5-Dichloro-4-methylsulfonylphenyl)-O,O-diethyl thiophosphate

Chlorthiophos-sulfone (CAS 25900-20-3) reference standard from WITEGA Laboratorien Berlin-Adlershof GmbH supports LC-MS/MS and GC-MS quantification, traceability, calibration, method validation, and confirmatory analysis. Related topics include pesticide residue calibration standard, LC-MS/MS pesticide analysis, GC-MS confirmation standard, traceability certified material, method validation standard, multi-residue method development.

This high-purity material provides consistent response factors across batches. You can build reliable calibration curves and low-level detection limits. It enables matrix-matched calibration and recovery studies with confidence. Use it to optimize extraction, separation, and ionization when developing multi-residue workflows.

• Quantify target residues with stable, reproducible results by LC-MS/MS.
• Confirm identities with GC-MS or tandem MS transitions.
• Validate accuracy, precision, linearity, and selectivity in fit-for-purpose methods.
• Demonstrate traceability through documented preparation and batch records.
• Support proficiency testing and routine system suitability checks.

Typical users include regulated laboratories, pharmaceutical research groups, residue control programs, and metabolism studies teams. The material fits screening and confirmatory methods. It also serves multi-residue method development where robustness matters.
