Description

(+)-Abscisic Acid CAS NO 21293-29-8 is a high-purity, naturally occurring plant hormone (phytohormone) crucial for regulating plant growth and stress responses. This enantiomerically pure compound is essential for advanced agricultural research and the development of next-generation plant growth regulators. It is primarily utilized by agrochemical R&D laboratories, plant physiology researchers, and manufacturers of specialty biostimulants and plant protection products seeking to enhance crop tolerance to abiotic stresses like drought and salinity.

Application

• Plant Physiology & Stress Response Research: Fundamental studies on stomatal closure, seed dormancy, and adaptation to environmental stressors such as drought, cold, and salinity.
• Agrochemical Formulation R&D: A key active ingredient or reference standard in the development of novel plant growth regulators and biostimulants aimed at improving crop resilience and water-use efficiency.
• Seed Treatment Technology: Used in research to modulate seed dormancy and improve germination uniformity under challenging conditions.
• Horticulture & Floriculture: Investigation of applications to manage plant growth, delay senescence, and improve post-harvest quality in ornamental plants and fruits.
• Biotechnology & Synthetic Biology: Serves as a critical standard and reagent in metabolic engineering studies aimed at understanding and manipulating plant hormone pathways.
• Academic & Institutional Research: A vital biochemical tool for universities and government research institutes conducting cutting-edge plant science.
