Description

Malathiondicarboxylicacid CAS NO 1190-28-9 is a key carboxylic acid derivative and a primary metabolite of the organophosphate insecticide malathion. This compound is of significant importance in analytical chemistry and environmental science as a reference standard for monitoring malathion degradation and exposure. It serves as a critical intermediate for researchers and manufacturers developing detection methods, studying metabolic pathways, and ensuring regulatory compliance in agricultural and environmental safety.

Application

• Analytical Reference Standard: Primary use as a certified standard for the quantification and confirmation of malathion and its metabolites in environmental and biological samples via HPLC, GC-MS, or LC-MS.
• Environmental Monitoring: Essential for testing laboratories analyzing soil, water, and air samples to assess malathion contamination levels and degradation rates.
• Metabolic Pathway Research: Used in biochemical and toxicological studies to investigate the metabolism and detoxification pathways of malathion in humans, animals, and insects.
• Pesticide Residue Analysis: Critical for food safety laboratories to develop and validate methods for detecting malathion residues on crops and in food products to ensure compliance with MRLs (Maximum Residue Limits).
• Forensic Toxicology: Employed as a calibrant in forensic analyses to determine malathion exposure in cases of accidental or intentional poisoning.
• Quality Control for Agrochemicals: Used by manufacturers of malathion-based formulations to monitor impurity profiles and ensure batch-to-batch consistency and purity.
• Biomarker Development: Serves as a precursor or standard for synthesizing conjugates used to develop immunoassays for rapid detection of malathion exposure.
