Propaphos

O,O’-Dipropyl-O’’-(4-methylthiophenyl) phosphate

Propaphos (CAS 7292-16-2) is a high-purity reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. It supports robust LC-MS/MS calibration standard workflows and precise GC-MS quantification. Choose this material when you need traceability, consistent calibration, and reliable method validation for pesticide residue testing and related studies.

Each reference standard lot is manufactured under rigorous quality controls by WITEGA Laboratorien Berlin-Adlershof GmbH. Clear documentation enables full traceability from raw material to final batch. This makes it straightforward to integrate into SOPs for regulated laboratories and to demonstrate data integrity during audits. Furthermore, its stability and purity help reduce matrix-related variability and improve confirmatory analysis.

Use this reference standard to streamline analytical quantification across LC-MS/MS or GC-MS platforms. It supports tuning, calibration curve construction, performance checks, and ongoing system suitability. As a result, your laboratory can achieve repeatable results with lower uncertainty. It also fits multi-residue method development, where consistency and comparability are essential across batches and instruments.

Typical applications include:

• Residue control in food, feed, and environmental matrices
• Pharmaceutical research and metabolism studies
• Regulated laboratory workflows and quality control programs
• Method validation and verification across LC-MS/MS and GC-MS
• Confirmatory analysis for compliance reporting
• Multi-residue method development and robustness testing

Key advantages:

• Traceable concentration with batch-specific documentation
• Optimized for LC-MS/MS and GC-MS quantification
• Supports calibration, method validation, and confirmatory analysis
• Consistent performance for routine residue control
• Ready to integrate into regulated workflows

Rely on this Propaphos reference standard to improve accuracy, strengthen data defensibility, and accelerate decision-making in your analytical pipeline.
