Description

β-Endosulfan D4 is a high-purity, deuterium-labeled internal standard critical for modern analytical chemistry. This stable isotope-labeled compound is essential for achieving accurate quantification and reliable data in complex matrices, ensuring method precision and regulatory compliance. It is primarily used by analytical laboratories, environmental testing facilities, and agrochemical researchers conducting residue analysis and metabolic studies.

Application

• Internal Standard for Mass Spectrometry (GC-MS/LC-MS): Used for the precise quantification of Endosulfan and its metabolites in environmental and biological samples.
• Environmental Monitoring: Critical in the analysis of soil, water, and air samples for pesticide residue tracking and regulatory compliance.
• Food Safety Testing: Employed in residue analysis to ensure food products meet maximum residue level (MRL) standards set by global authorities.
• Metabolic and Pharmacokinetic Studies: Serves as a tracer in research to study the absorption, distribution, metabolism, and excretion (ADME) of Endosulfan.
• Method Development and Validation: A key component in developing and validating robust analytical methods according to ISO 17025 or FDA guidelines.
• Quality Control and Assurance: Used in-house by agrochemical manufacturers to ensure batch-to-batch consistency and product purity.
