Description

Homoyessotoxin Di‐Sodium Salt Standard Solution is a high-purity certified reference material (CRM) used for the precise calibration and validation of analytical methods. This standard is critical for ensuring accurate quantification and quality control in research and regulatory testing environments. It is primarily required by analytical laboratories, contract research organizations (CROs), and food safety agencies involved in marine biotoxin monitoring and pharmaceutical research.

Application

• Analytical Method Development and Validation: Serves as a primary standard for establishing calibration curves in Liquid Chromatography-Mass Spectrometry (LC-MS/MS) and HPLC methods.
• Marine Biotoxin Research: Used in the study of yessotoxin analogs, their toxicity profiles, and metabolic pathways in marine organisms.
• Food Safety Testing: Essential for the accurate detection and quantification of homoyessotoxin in shellfish and seafood to comply with international safety regulations.
• Quality Control & Assurance: Employed as a benchmark in laboratory proficiency testing and for verifying the accuracy of in-house testing protocols.
• Pharmaceutical Reference Standard: Used in pharmacological studies investigating the effects of marine neurotoxins.
• Environmental Monitoring: Applied in programs monitoring harmful algal blooms (HABs) and their toxin profiles in coastal waters.
