Isofenphos methyl

2-(Isopropylamino-methoxy-thiophosphoryloxy) benzoic acid isopropyl ester

Isofenphos methyl (CAS 99675-03-3) is an organophosphate pesticide 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. This organophosphate pesticide reference standard enables method validation in regulated laboratories, while ensuring traceability and consistent calibration.

Develop robust calibration curves with this reference standard to achieve accurate quantification across complex matrices. Moreover, laboratories can verify recovery and linearity, then document traceability for audits. The material is designed for LC-MS/MS and GC-MS methods, which helps reduce matrix effects and enhances reproducibility. Additionally, lot-specific data support routine quality control and confirmatory analysis.

Typical applications include:

• Residue control in food, feed, and environmental samples
• Pharmaceutical research and metabolism studies with relevant matrices
• Multi-residue method development and optimization
• Regulated laboratory workflows requiring calibration and traceable verification

As a high-quality reference standard from WITEGA, Isofenphos methyl (CAS 99675-03-3) helps maintain compliance across routine and investigative workflows. Use it to establish and verify identification criteria, set retention time windows, and confirm transitions. Furthermore, apply it to check batch-to-batch consistency and strengthen data integrity in confirmatory analysis.

Key benefits:

• Reliable calibration for LC-MS/MS and GC-MS
• Traceability supporting regulatory requirements
• Supports method validation, instrument suitability, and stability checks
• Fits multi-residue strategies and targeted quantification

In short, this reference standard from WITEGA Laboratorien Berlin-Adlershof GmbH streamlines calibration, strengthens traceability, and ensures precise quantification throughout your analytical workflow.
