Description

Aflatoxin B2 is a potent mycotoxin and a secondary metabolite produced by certain strains of *Aspergillus* fungi. It is a critical reference standard and analytical reagent used globally for the accurate detection, quantification, and research of aflatoxin contamination. This high-purity compound is essential for laboratories and industries focused on food safety, agricultural quality control, and toxicological studies. Professionals in analytical chemistry, regulatory affairs, and product development rely on it to ensure compliance and protect public health.

Application

• Analytical Reference Standard: Primary use as a certified calibrant for the quantitative analysis of aflatoxins in complex matrices via HPLC, LC-MS/MS, and ELISA techniques.
• Food & Feed Safety Testing: Calibration and method validation for monitoring aflatoxin B2 levels in nuts, grains, cereals, spices, and animal feed to comply with international regulatory limits (e.g., FDA, EU, Codex Alimentarius).
• Quality Control & Assurance: Serves as a system suitability check and quality control standard for in-house laboratories and commercial testing services.
• Toxicological & Biomedical Research: Used in studies investigating the metabolism, carcinogenicity, and toxicological mechanisms of aflatoxins.
• Method Development & Validation: Critical for developing, optimizing, and validating new analytical methods for mycotoxin detection.
• Pharmaceutical Impurity Testing: Employed in the analysis of herbal medicines and botanicals where fungal contamination is a concern.
• Proficiency Testing & Certification: Used by accreditation bodies and providers of certified reference materials (CRMs) for laboratory inter-comparison and certification programs.

Quality Control

Our Aflatoxin B2 is manufactured and handled under strict quality-controlled conditions to ensure the highest purity and consistency for critical analytical applications. Each batch is rigorously analyzed using state-of-the-art techniques like HPLC with UV/fluorescence detection and is accompanied by a comprehensive Certificate of Analysis (COA). The COA provides batch-specific data on purity, identity confirmation, and related substances. We support compliance with ISO 17034 (Reference Materials) and ISO/IEC 17025 (Testing Laboratories) standards.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C. For long-term storage, consider storing at -20°C under an inert atmosphere. The container should be kept in a dry, well-ventilated area designated for toxic materials. Allow the sealed vial to equilibrate to room temperature before opening to prevent condensation.
