Description

4,4'-Ddt D8 is a deuterated isotopologue of the classic organochlorine compound 4,4'-DDT, specifically designed for analytical and research applications. This stable isotope-labeled standard is essential for ensuring accuracy and reliability in quantitative mass spectrometry, where it serves as an internal reference to correct for variations in sample preparation and instrument response. It is a critical tool for environmental testing laboratories, regulatory agencies, and research institutions conducting trace-level analysis of pesticide residues, environmental fate studies, and method development and validation.

Application

• Internal Standard for Mass Spectrometry (MS): Primary use as a quantitative internal standard in GC-MS or LC-MS/MS analysis for 4,4'-DDT and related metabolites.
• Environmental Monitoring and Analysis: Enables precise quantification of DDT and its degradation products in soil, water, sediment, and biota samples for pollution studies.
• Food Safety and Residue Testing: Used in accredited laboratories to monitor and ensure compliance with maximum residue limits (MRLs) for pesticides in agricultural products.
• Clinical and Toxicological Research: Facilitates the study of DDT bioaccumulation, metabolism, and long-term health effects in epidemiological and forensic toxicology.
• Method Development and Validation: Serves as a critical reference material for developing, optimizing, and validating new analytical protocols according to ISO 17025 or similar standards.
• Quality Assurance/Quality Control (QA/QC): Employed in laboratory proficiency testing and as a system suitability check to ensure analytical instrument performance and data integrity.

Quality Control

Our 4,4'-Ddt D8 is produced under strict quality management systems to ensure the high chemical and isotopic purity required for analytical reference standards. Each batch is characterized by advanced spectroscopic and chromatographic techniques, including NMR, GC-MS, and HPLC, to confirm identity, isotopic enrichment (typically ≥98 atom % D), and chemical purity. A comprehensive Certificate of Analysis (COA) is provided, detailing all specifications and traceability information to support ISO/IEC 17025 accredited testing and GLP-compliant research.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C) in a dry, well-ventilated area. For long-term stability, storage at 2-8°C is recommended. Keep away from heat and incompatible materials.
