Ethoxyquin-Dimer

6,6’-Diethoxy-2,2,2’,2’, 4,4’-hexamethyl-2H-1’,2’-dihydro-1,8’-biquinoline

Ethoxyquin-Dimer (CAS 74681-77-9) reference standard enables precise identification and quantification in modern analytical workflows. This antioxidant residue reference material supports reliable screening and verification. It is produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH with lot-specific documentation. Use it to streamline LC-MS/MS and GC-MS assays. Consequently, your lab achieves consistent performance and clear reporting.

This reference standard delivers traceability aligned to stated purity and content. It improves calibration curves, method validation, and confirmatory analysis. Analysts can prepare matrix-matched calibrators and spikes with confidence. The material performs in low-level residue control and metabolism studies. For LC-MS/MS or GC-MS, stable response and clean spectra reduce uncertainty.

Typical applications include:

• Regulated laboratories performing residue monitoring and compliance testing.
• Pharmaceutical research exploring oxidative degradation pathways and metabolism.
• Food and feed testing developing multi-residue methods.
• Contract research organizations that require robust QA and QC workflows.
• Academic groups teaching advanced quantitation and confirmation strategies.

Each batch is manufactured and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH under strict quality controls. The Ethoxyquin-Dimer (CAS 74681-77-9) reference standard ships with a certificate of analysis, recommended storage, and handling guidance. It integrates smoothly into routine calibration sequences, supports traceability across instruments, and helps document compliance with SOPs. Select this material to enhance reproducibility and confidence from initial screening through confirmatory analysis.
