Description

Dihydromicrocystin Lr is a reduced, dihydro derivative of the potent cyanobacterial hepatotoxin microcystin-LR. This compound is of significant value as a key reference standard and analytical tool in environmental and toxicological research. It is primarily required by analytical laboratories, research institutions, and environmental monitoring agencies for the precise quantification, method development, and toxicological study of microcystin variants in water samples.

Application

• Analytical Reference Standard: Primary use for calibrating analytical instruments (HPLC, LC-MS/MS) for accurate detection and quantification of microcystins.
• Toxicology Research: Used in studies to investigate the comparative toxicity, metabolic pathways, and biochemical mechanisms of microcystin derivatives.
• Method Development & Validation: Essential for developing, optimizing, and validating new analytical methods for cyanotoxin monitoring in drinking and environmental water.
• Quality Control Testing: Serves as a system suitability check and a critical component in the quality control of water testing laboratories.
• Environmental Monitoring: Supports programs aimed at assessing and managing risks associated with harmful algal blooms (HABs).
• Biochemical Research: Used as a probe to study protein phosphatase inhibition and other specific enzyme interactions related to the microcystin family.
