Description

Rac 8’-Acetylene Abscisic Acid Methyl Ester is a synthetic derivative of the key plant hormone abscisic acid (ABA), featuring an acetylene modification at the 8' position. This compound serves as a crucial research-grade biochemical tool for studying ABA signaling pathways, stress responses, and plant development. It is primarily utilized by agrochemical researchers, plant biologists, and specialty chemical manufacturers engaged in the development of novel plant growth regulators and stress-protectant formulations.

Application

• Plant Physiology & Biochemistry Research: A key reference standard and active probe for investigating the molecular mechanisms of abscisic acid (ABA) action, receptor binding, and signal transduction.
• Agrochemical R&D: Used as a lead compound or intermediate in the synthesis and screening of next-generation plant growth regulators aimed at improving drought tolerance and stress resilience in crops.
• Mode-of-Action Studies: Essential for elucidating the structure-activity relationships (SAR) of ABA analogs to design more potent or stable agrochemical agents.
• Seed Technology Development: Investigated for applications in seed priming and coating technologies to enhance germination uniformity and early seedling vigor under abiotic stress.
• Academic & Institutional Research: Supplied to universities and research institutes for fundamental studies on plant hormone biology and environmental adaptation.
• Standards & Calibration: Serves as a high-purity analytical standard for the quantification of ABA and its derivatives in plant tissues and commercial products via HPLC or LC-MS.
