Description

Patulin(Rg) is a mycotoxin and a secondary metabolite produced by certain species of *Penicillium*, *Aspergillus*, and *Byssochlamys* molds. This compound is of critical importance as a certified reference material (CRM) for analytical method development, validation, and quality control in food and feed safety testing. It is essential for laboratories in the food and beverage, agricultural, and regulatory compliance sectors requiring precise quantification of patulin contamination, particularly in apple products, fruit juices, and other susceptible commodities.

Application

• Primary use as a certified reference standard for the calibration of analytical instruments.
• Method development and validation for patulin detection in compliance with global food safety regulations (e.g., EU, FDA, China GB standards).
• Quality control and proficiency testing in food and beverage testing laboratories.
• Research on mycotoxin toxicity, biosynthesis pathways, and degradation studies.
• Preparation of spiked samples for recovery studies and internal quality assurance programs.
• Use in academic and institutional research focused on mycology and foodborne contaminants.

Quality Control

Our Patulin(Rg) reference material is produced and controlled under a strict quality management system. Each batch is characterized using a combination of orthogonal techniques including HPLC, NMR, and mass spectrometry to ensure identity, purity, and stability. A comprehensive Certificate of Analysis (COA) is supplied with each product, providing batch-specific data traceable to primary standards. Our quality commitment supports compliance with ISO/IEC 17025 and ISO 17034 requirements for reference material producers.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C. This material is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). For long-term storage, consider storing desiccated under an inert atmosphere such as argon or nitrogen at -20°C.
