Description

Desmethyl Norflurazon-D4 is a deuterium-labeled analog of the herbicide metabolite desmethyl norflurazon, specifically designed for use as an internal standard in analytical chemistry. This high-purity compound is critical for ensuring the accuracy and reliability of quantitative mass spectrometry methods, particularly in complex matrices. It is an essential tool for researchers and quality control laboratories in the agrochemical, environmental monitoring, and food safety sectors who require precise quantification of norflurazon and its metabolites.

Application

• Primary use as an internal standard for the quantification of norflurazon and its metabolites via LC-MS/MS and GC-MS.
• Method development and validation in environmental residue analysis of soil and water samples.
• Quality control and assurance in agrochemical research and manufacturing processes.
• Metabolite profiling and degradation studies in crop science and plant physiology.
• Supporting regulatory compliance and testing for food safety (pesticide residue monitoring).
• Use in clinical and toxicological research investigating human or animal exposure.

Quality Control

Our Desmethyl Norflurazon-D4 is manufactured under strict quality control protocols to ensure high isotopic purity and chemical stability, essential for its role as an analytical standard. Each batch is characterized by advanced spectroscopic and chromatographic techniques, including NMR and HPLC-MS. A comprehensive Certificate of Analysis (COA) detailing isotopic enrichment, chemical purity, and analytical results is provided with every shipment to support your method validation and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled in a dry environment to maintain stability and purity. For long-term storage, consider desiccation.
