Description

Abscisic Acid Methylester is a synthetic derivative of the key plant hormone abscisic acid (ABA), designed for enhanced stability and bioactivity. This compound is a critical research tool and active ingredient for modulating plant stress responses, growth regulation, and developmental processes. It is essential for agricultural research institutions, plant science laboratories, and manufacturers developing next-generation plant growth regulators and biostimulants for global crop production.

Application

• Plant Physiology & Stress Response Research: A fundamental tool for studying ABA-mediated signaling pathways, stomatal closure, drought tolerance, and seed dormancy in controlled laboratory environments.
• Agricultural Biotechnology: Used in the development and screening of novel crop varieties with enhanced abiotic stress resistance (e.g., to drought, salinity, cold).
• Plant Growth Regulator (PGR) Formulations: Serves as a key active ingredient in advanced PGRs aimed at improving crop yield, quality, and resilience under suboptimal growing conditions.
• Seed Treatment Solutions: Incorporated into coatings or priming solutions to improve germination uniformity and seedling vigor under stress.
• Horticulture & Floriculture: Applied to manage growth, delay senescence, and improve post-harvest quality in ornamental plants, fruits, and vegetables.
• Synthesis of ABA Analogs: Acts as a crucial chemical intermediate or reference standard for synthesizing and evaluating new ABA-like compounds with tailored properties.
