In the realm of fine chemicals and specialized reagents, understanding the precise properties and applications of a compound is crucial for researchers and industry professionals alike. rac-GR24, identified by CAS number 76974-79-3, is a synthetic strigolactone analog that has garnered significant attention in plant biology and agricultural research. This article delves into the chemical characteristics and multifaceted uses of rac-GR24, highlighting its importance as a research tool and potential agricultural agent.

Chemically, rac-GR24 is a terpenoid lactone with the molecular formula C17H14O5 and a molecular weight of approximately 298.29 g/mol. It exists as a solid, typically appearing as a white to off-white powder. The compound exhibits solubility in common organic solvents such as DMSO, ethanol, and methanol, making it amenable to various experimental preparations. Its stability is generally good under recommended storage conditions, often requiring storage at low temperatures (e.g., -20°C or below) and protection from light to maintain its integrity. When considering a purchase, inquiring about stability data from the manufacturer is advisable.

The primary utility of rac-GR24 stems from its role as a synthetic mimic of natural strigolactones. These plant hormones are involved in regulating a wide array of developmental processes, including the inhibition of shoot branching, modulation of root growth, and the establishment of symbiotic relationships with arbuscular mycorrhizal fungi (AMF). Researchers purchase rac-GR24 to investigate these phenomena, enabling precise control over strigolactone signaling in experimental systems.

One of the most prominent applications of rac-GR24 is in studies concerning plant architecture. By applying this synthetic analog, scientists can effectively study the mechanisms by which plants control shoot branching, a critical factor in determining crop yield and biomass. This research is vital for developing strategies to optimize plant growth and productivity. Many suppliers offer rac-GR24 in various purities, so it's important for buyers to specify their needs when requesting a quote.

Furthermore, rac-GR24 is instrumental in research related to plant-microbe interactions. It plays a key role in mediating the symbiotic relationship between plants and AMF, which enhances nutrient uptake and plant health. By understanding these interactions through studies with rac-GR24, scientists can develop methods to promote these beneficial symbioses in agricultural settings, potentially reducing the need for synthetic fertilizers. Manufacturers often highlight this application when describing their product.

Another significant application is in the control of parasitic weeds, such as Striga species, which severely impact crop yields in many regions. Strigolactones are known to stimulate the germination of these parasitic seeds. rac-GR24 is used to study this germination response, paving the way for innovative strategies to manage parasitic weeds and protect crops. The availability of rac-GR24 from reliable manufacturers ensures that researchers have access to this critical tool for developing agricultural solutions.

When sourcing rac-GR24, it is important to consider reputable manufacturers and suppliers who can provide detailed specifications, safety data sheets (SDS), and Certificates of Analysis (CoA). Companies based in China, for instance, are prominent suppliers of such fine chemicals, often offering competitive pricing. Whether for fundamental research or applied agricultural development, rac-GR24 stands as a vital synthetic compound that continues to unlock new possibilities in plant science.
