Description

8'-Oxo-6-Hydroxydihydrophaseic Acid is a specialized oxidized derivative of dihydrophaseic acid, a key metabolite in the abscisic acid (ABA) catabolic pathway. This compound is of significant interest for its role as a biochemical tool in plant physiology and stress response research. It is primarily utilized by researchers and developers in the agrochemical and plant biotechnology sectors for studying hormone metabolism, developing plant growth regulators, and creating stress-tolerant crop varieties.

Application

• Plant Hormone Research: A critical reference standard and analytical tool for studying the catabolism and signaling pathways of abscisic acid (ABA).
• Agrochemical Development: Used in the research and screening of novel plant growth regulators (PGRs) and stress-mitigating agents.
• Metabolite Analysis: Serves as a high-purity standard for the quantification of ABA metabolites in plant tissues via HPLC-MS or GC-MS.
• Biochemical Studies: Employed in enzymatic assays to investigate the activity of cytochrome P450 monooxygenases and other enzymes involved in ABA metabolism.
• Seed Dormancy & Germination Research: Applied in studies to understand the molecular mechanisms controlling seed dormancy, germination, and seedling establishment.
• Plant Stress Physiology: Used to elucidate plant adaptive responses to abiotic stresses such as drought, salinity, and cold.
