Description

Carboxyfenitrothion is an organophosphorus compound and a key metabolite or derivative of the insecticide fenitrothion. This chemical is significant for its role in environmental fate studies, analytical method development, and as a reference standard in toxicology and residue analysis. It is primarily required by research institutions, analytical laboratories, and agrochemical companies engaged in environmental monitoring, regulatory compliance testing, and the development of safer pesticide formulations.

Application

• Analytical Reference Standard: Used as a certified standard for the accurate quantification of fenitrothion and its metabolites in environmental and biological samples via HPLC, GC-MS, or LC-MS.
• Environmental Fate and Metabolism Studies: Employed in research to understand the degradation pathways, persistence, and transformation products of fenitrothion in soil and water systems.
• Toxicological Research: Serves as a key material for investigating the toxicity profile, metabolic pathways, and potential health impacts of fenitrothion breakdown products.
• Agrochemical Research & Development: Utilized in the synthesis and evaluation of new pesticide formulations or in studies aimed at improving the efficacy and environmental profile of existing organophosphates.
• Regulatory Compliance and Residue Analysis: Essential for testing agricultural products, water, and soil to ensure compliance with maximum residue limits (MRLs) set by global regulatory bodies.

Quality Control

Our Carboxyfenitrothion is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing to ensure high purity and consistency, with specifications typically meeting or exceeding standard requirements for research and analytical applications. A detailed Certificate of Analysis (COA) providing purity, identity confirmation, and impurity profiles is supplied with every shipment to guarantee traceability and reliability for your critical work.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at controlled room temperature (15-25°C). This material is easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, and open flame.
