Description

Terbutryn-D5 (Ethyl-D5) is a deuterated isotopologue of the herbicide terbutryn, where five hydrogen atoms are replaced by deuterium, specifically on the ethyl side chain. This stable isotope-labeled compound is essential for use as an internal standard in quantitative mass spectrometry, ensuring high accuracy and precision in analytical measurements. It is primarily needed by analytical laboratories, environmental testing facilities, and agrochemical research institutions conducting residue analysis, metabolic studies, and method development.

Application

• Internal Standard for LC-MS/MS and GC-MS analysis of terbutryn and related triazine herbicides.
• Quantitative reference material in environmental monitoring for soil and water contamination studies.
• Use in agrochemical research for tracing metabolic pathways and degradation studies.
• Calibration standard for high-accuracy analytical method development and validation.
• Critical component in residue analysis for food safety and regulatory compliance testing.
• Tool for pharmacokinetic and toxicological research in scientific studies.

Quality Control

Our Terbutryn-D5 (Ethyl-D5) is produced and tested to meet the stringent requirements for isotopic purity and chemical purity demanded by advanced analytical applications. Each batch undergoes rigorous quality testing, including NMR and mass spectrometry for isotopic enrichment verification and HPLC for chemical purity. Certificates of Analysis (COA) detailing batch-specific data for isotopic purity (e.g., D5 > 98 atom % D), chemical purity, and solvent content are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C or as indicated on the label or COA. This product is hygroscopic (moisture-sensitive) and should be handled under anhydrous conditions to maintain stability.
