Description

Altertoxin I is a potent mycotoxin belonging to the perylene quinone class of fungal metabolites. This compound is of significant interest in research and analytical chemistry due to its role as a secondary metabolite produced by various *Alternaria* species. It serves as a critical reference standard and research material for scientists and quality control laboratories in the food safety, agricultural, and toxicology sectors, enabling the accurate detection, quantification, and study of mycotoxin contamination.

Application

• Analytical Reference Standard: Primary use as a high-purity certified reference material (CRM) for calibrating analytical instrumentation such as HPLC, LC-MS/MS, and ELISA kits.
• Food Safety Research: Used in method development and validation studies to monitor and control Alternaria mycotoxin contamination in grains, fruits, vegetables, and other food commodities.
• Toxicological Studies: Employed in in-vitro and in-vivo research to investigate the cytotoxicity, genotoxicity, and overall toxicological profile of altertoxins.
• Phytopathological Research: Serves as a tool in plant pathology to study the role of mycotoxins in plant-fungus interactions and disease development.
• Quality Control & Assurance: Essential for pharmaceutical and agricultural QC labs to ensure the accuracy and reliability of mycotoxin screening programs.
• Regulatory Compliance Testing: Supports testing to meet international food safety regulations and guidelines concerning mycotoxin limits.

Quality Control

Every batch of Altertoxin I is manufactured and handled under strict quality management protocols. Our products undergo rigorous identity confirmation, purity analysis, and stability testing to ensure they meet the exacting standards required for research and analytical applications. A comprehensive Certificate of Analysis (COA), detailing batch-specific results for purity, identity, and related substances, is provided with each shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C for long-term stability. Allow the product to equilibrate to room temperature before opening to prevent moisture condensation. The container should be kept in a cool, dry, and well-ventilated area dedicated for the storage of reference standards.
