Fluorescent brightener ER-II

2-[2-[4-[2-(4-Cyanophenyl)ethenyl]phenyl]ethenyl]benzonitrile

Fluorescent brightener ER-II (CAS 13001-38-2) is a high-purity reference standard for LC-MS/MS and GC-MS quantification. This optical whitening agent standard supports traceable calibration, method validation, and confirmatory analysis across demanding matrices. It is produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH for dependable traceability.

Designed for routine and research workflows, this material helps build reliable calibration curves and quality control checks. Consequently, you can verify recovery, linearity, and limits of quantification with confidence. Moreover, it enables consistent data across laboratories and platforms.

Key features:

• High chemical purity and well-documented identity
• Optimized for LC-MS/MS and GC-MS selectivity and response
• Traceable preparation supports robust calibration and trending
• Lot-specific documentation for transparency and compliance
• Clear handling guidance for consistent day-to-day performance

Typical applications:

• Regulated laboratories ensuring reliable routine quantification
• Pharmaceutical research supporting discovery and development
• Residue control programs requiring traceable results
• Metabolism studies tracking transformation products
• Multi-residue method development across complex matrices
• Confirmatory analysis to verify screening outcomes

Use this reference standard to establish calibration levels, prepare QC samples, and run system suitability tests. Then confirm results with independent batches to document reproducibility. Its consistent response helps reduce uncertainty and supports coherent reporting.

Each lot is supported by comprehensive documentation that facilitates audits and method transfers. Therefore, analysts can compare performance over time and between instruments. For ordering information, technical support, and availability, please contact WITEGA Laboratorien Berlin-Adlershof GmbH.
