N-Ethyl-D₅-1-[2-[4-(2-phenyldiazenyl)phenyl]diazenyl]-2-naphthalenamine

Sudan Red 7B D5 is a deuterated reference standard and azo dye reference material produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH. Optimized for LC-MS/MS and GC-MS, this deuterated calibration standard enables accurate quantification, robust traceability, and reliable calibration. Use it to streamline method development and speed up confirmatory analysis while maintaining high data integrity.

Built for modern analytical workflows, this reference standard helps you establish linear calibration ranges, evaluate recovery, and verify matrix effects. It supports method validation steps such as precision, accuracy, selectivity, and LOQ assessments. Furthermore, it ensures consistent performance across batches, which strengthens comparability and long-term trending.

• High-purity reference standard suitable for LC-MS/MS and GC-MS quantification
• Excellent lot-to-lot consistency for traceable calibration
• Clear documentation to support method validation and quality audits
• Ideal for confirmatory analysis and proficiency testing

Typical use cases include regulated laboratories, pharmaceutical research, residue control, metabolism studies, and multi-residue method development. Because it is produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH, you can integrate it into SOPs with confidence and meet stringent quality expectations.

• Regulatory compliance support in routine surveillance labs
• Pharmaceutical and toxicological research requiring stable quantification
• Residue monitoring across complex matrices
• Metabolism and degradation pathway investigations
• Multi-residue screening with precise calibration and verification

Store the material as recommended and document each use to maintain traceability. Apply appropriate dilution schemes and matrix-matched calibration for complex samples. With Sudan Red 7B D5, you can quickly confirm results, reduce re-runs, and improve decision-making across your analytical pipeline.
