Description

Sudan-Ii-D6 is a deuterated internal standard of the synthetic azo dye Sudan II, specifically designed for high-precision analytical applications. This compound is essential for ensuring accurate quantification and method validation in mass spectrometry-based analyses, providing critical reliability in sensitive detection workflows. It is primarily utilized by analytical laboratories and research institutions in the food safety, environmental monitoring, and forensic chemistry sectors where trace-level analysis of Sudan dyes is required.

Application

• Internal Standard for Mass Spectrometry (MS): Used as a deuterium-labeled internal standard for the accurate quantification of Sudan II via LC-MS/MS or GC-MS, correcting for matrix effects and instrument variability.
• Food Safety Testing: Critical for the analysis of illegal Sudan dyes in food products like chili powder, palm oil, and spices, ensuring compliance with global food safety regulations (e.g., EU, FDA).
• Method Development and Validation: Serves as a key reference material for developing, optimizing, and validating analytical methods in quality control and research laboratories.
• Forensic and Dye Analysis: Employed in forensic science for the identification and sourcing of dyes in materials and in studies investigating the metabolism and degradation of azo dyes.
• Environmental Analysis: Applied in monitoring studies to detect and quantify Sudan dye contaminants in water and soil samples.
• Pharmaceutical Research: Used in research settings studying the toxicology and pharmacokinetics of azo dye compounds.
