Description

(S)-Patulin Methyl Ether CAS NO 123251-09-2 is a chiral derivative of patulin, a mycotoxin, and serves as a critical reference standard and synthetic intermediate in analytical and organic chemistry. Its precise stereochemistry makes it an essential tool for method development and validation in food safety and toxicology research. This compound is primarily required by analytical laboratories, research institutions, and pharmaceutical developers focusing on mycotoxin analysis, chiral synthesis, and metabolic studies.

Application

• Analytical Reference Standard: Primary use for calibrating and validating HPLC, LC-MS, and GC-MS methods for patulin and related mycotoxin detection in food and agricultural products.
• Food Safety Research: Critical for studying the metabolism, toxicity, and degradation pathways of patulin to ensure regulatory compliance and consumer safety.
• Organic Synthesis: Serves as a key chiral building block or precursor in the synthesis of more complex natural products or biologically active molecules.
• Toxicology Studies: Used in research to investigate the specific biological effects and mechanisms of action of stereoisomers of patulin derivatives.
• Method Development: Essential for developing new, more sensitive, and selective analytical techniques for mycotoxin screening in complex matrices.
• Quality Control: Employed by manufacturers and testing labs as an in-house control standard to ensure the accuracy and reliability of their analytical results.

Quality Control

Every batch of (S)-Patulin Methyl Ether is produced and analyzed under strict quality management protocols to ensure identity, purity, and stability. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request, providing detailed results for chiral purity, chemical purity, and related substances.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and light-sensitive (store away from light); therefore, containers must be kept tightly sealed in a desiccated environment to prevent degradation. For long-term storage, consider storing under an inert atmosphere.
