  • Applications

    7'-Hydroxyabscisic acid (CAS 91897-25-5) is primarily encountered in agrochemical and plant biology contexts as an analytical standard and research reagent. In practice, it serves as an analytical reference for ABA and related metabolites in plant hormone profiling, enabling LC-MS quantification in crop physiology studies. It is also used as a research reagent to probe ABA signaling pathways and enzyme interactions in plant biochemistry. As a potential intermediate, it can be used in the synthesis and evaluation of ABA analogs and related agrochemical candidates in R&D programs. Additionally, it may function as a chemical probe or substrate in enzymology studies of ABA metabolism, supporting basic research on plant stress responses. Its use is typically limited to laboratory research and development, with applications governed by relevant regulations.
