Bis-(4-dimethylamino-phenyl)-phenyl-D₅-carbenium picrate

Malachite green D5 picrate (CAS 1258668-21-1) is a deuterated dye reference standard produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. It supports LC-MS/MS and GC-MS analytical quantification, traceability, calibration, method validation, and confirmatory analysis across complex matrices. Therefore, it helps laboratories achieve reliable performance and consistent recoveries.

This high-purity reference standard is optimized for robust response in modern mass spectrometry workflows. Each lot ships with comprehensive documentation for identity and purity, enabling traceable reporting and reproducible results. Moreover, the isotopic labeling delivers improved selectivity and reduced interferences in challenging samples.

• Suitable for LC-MS/MS and GC-MS calibration curves
• Supports method validation and system suitability
• Enables confirmatory analysis with clear identification criteria
• Provides traceability with lot-specific documentation
• Designed for multi residue method development

Typical use cases include regulated laboratories, pharmaceutical research, residue control programs, metabolism studies, and multi-residue screening. In addition, it aids routine quality control and investigation of degradation pathways.

• Regulated laboratories performing compliance testing
• Pharmaceutical research and discovery investigations
• Residue control in food, feed, and environmental samples
• Metabolism studies and transformation profiling
• Multi residue method development and optimization

For quantitative workflows, prepare matrix-matched calibration sets and spike controls using the reference standard. Build linear or weighted curves, verify accuracy with independent check levels, and evaluate recovery. Then confirm target identification using retention time, qualifier ratios, and spectral match criteria.

As a trusted supplier, WITEGA Laboratorien Berlin-Adlershof GmbH ensures consistent quality, dependable availability, and customer support for this reference standard. Choose Malachite green D5 picrate (CAS 1258668-21-1) to strengthen data integrity and simplify reporting.
