Description

Benomyl-D4 (Benzimidazole-4,5,6,7-D4) is a high-purity, stable isotope-labeled analog of the broad-spectrum benzimidazole fungicide Benomyl, specifically deuterated at the 4,5,6,7 positions of the benzimidazole ring. This compound is essential for use as an internal standard in advanced analytical methods, ensuring precise quantification and reliable data in complex matrices. It is primarily required by analytical laboratories, agrochemical research institutions, and environmental testing facilities engaged in method development, residue analysis, and metabolic studies.

Application

• Internal Standard for LC-MS/MS and GC-MS analysis of Benomyl and its metabolites in food, soil, and water samples.
• Quantitative reference material for isotope dilution mass spectrometry (IDMS) to ensure accuracy and compensate for matrix effects and instrument variability.
• Critical component in regulatory compliance testing and method validation for pesticide residue analysis in agricultural products.
• Tracer compound in environmental fate and metabolism studies to track the degradation and transformation pathways of Benomyl.
• Use in clinical and pharmacological research for studying the pharmacokinetics of benzimidazole-derived pharmaceuticals.
• Calibration standard for ensuring data integrity in Good Laboratory Practice (GLP) and ISO 17025 accredited laboratories.
