Description

Azoxystrobin-D4 is a deuterium-labeled internal standard specifically designed for quantitative analysis of azoxystrobin in complex matrices using liquid chromatography–tandem mass spectrometry (LC-MS/MS). It delivers exceptional analytical precision and accuracy by compensating for matrix effects, instrument variability, and extraction efficiency losses—critical for regulatory compliance and method validation. This compound is essential for laboratories engaged in pesticide residue testing across food safety, environmental monitoring, and agrochemical R&D sectors globally. Azoxystrobin-D4 CAS NO 1346606-39-0 is widely adopted by contract research organizations (CROs), government testing labs, and quality control departments requiring trace-level quantification with high reproducibility.

Application

• Internal standard for LC-MS/MS quantification of azoxystrobin residues in fruits, vegetables, cereals, and processed foods
• Reference material in method development and validation studies per ISO/IEC 17025 and SANTE/11813/2017 guidelines
• Quality control spike-in for multi-residue pesticide screening programs in national food surveillance systems
• Calibration standard in environmental analysis of soil, water, and sediment samples for agricultural runoff monitoring
• Supporting GLP-compliant toxicokinetic and metabolism studies in non-clinical agrochemical safety assessment
• Stable isotope dilution assay (SIDA) component for accurate determination of azoxystrobin degradation products

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request. Each batch is verified for isotopic enrichment (>98% D-incorporation at designated positions), chemical purity (≥98.5% by HPLC-UV), identity (NMR and HRMS confirmation), and absence of undeuterated azoxystrobin (≤0.3%). Testing adheres to ICH Q5, Q7, and ISO/IEC 17025 requirements for reference standards used in regulated analytical laboratories.

Storage

Preserve in a tightly closed container, protected from light. Store at 2–8 °C under inert atmosphere (argon or nitrogen) to prevent degradation. Due to its hygroscopic nature, maintain low-humidity conditions (<30% RH) and minimize exposure to ambient air during handling.
