Used in plant physiology research to study abscisic acid (ABA) metabolism and signaling pathways. Acts as a catabolic derivative of ABA, helping regulate ABA levels in plant tissues under stress conditions such as drought, salinity, and cold. Plays a role in understanding how plants control seed dormancy, stomatal closure, and stress responses. Also utilized as a reference standard in analytical methods like LC-MS and HPLC for identifying and quantifying ABA metabolites in plant samples.
