Description

Carbendazim D4 is a deuterium-labeled analog of the widely used systemic benzimidazole fungicide, carbendazim, specifically designed for analytical and research applications. This stable isotope-labeled compound is an essential internal standard for the precise and accurate quantification of carbendazim residues in complex matrices via advanced techniques like LC-MS/MS. It is critically needed by analytical laboratories, environmental monitoring agencies, and agrochemical research institutions engaged in method development, regulatory compliance testing, and metabolic studies to ensure data integrity and meet stringent quality standards.

Application

• Primary use as an internal standard for the quantitative analysis of carbendazim and its metabolites using mass spectrometry.
• Critical component in method development and validation for pesticide residue testing in food, soil, and water samples.
• Enables isotope dilution analysis to achieve high accuracy and compensate for matrix effects and analyte loss during sample preparation.
• Used in environmental fate and metabolism studies to track the degradation and transformation pathways of carbendazim.
• Supports regulatory compliance and quality control testing for agricultural products and export commodities.
• Facilitates clinical and toxicological research investigating the exposure and effects of benzimidazole fungicides.

Quality Control

Every batch of Carbendazim D4 is produced and analyzed under strict quality protocols to ensure the high chemical purity and isotopic enrichment required for trace-level analytical work. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request and provide detailed data on isotopic purity, chemical purity, and solvent content.

Storage

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