Acetosyringone, with the CAS number 2478-38-8, is a high - quality chemical compound. Chemically, its molecular formula is C₉H₁₀O₃, and it has a molecular weight of approximately 166.17 g/mol. This product is known for its high purity, which is carefully maintained during the manufacturing process to ensure optimal performance in various applications.
It is typically presented as a solid with a characteristic appearance. The compound is stable under normal storage conditions, but it is advisable to store it in a cool, dry place away from direct sunlight and incompatible materials.
Acetosyringone has several important uses in the scientific and industrial fields. In the field of plant biotechnology, it is widely used as an inducer of virulence genes in Agrobacterium - mediated plant transformation. This is crucial because it helps in the transfer of foreign DNA into plant cells, which is a fundamental step in genetic engineering of plants. By using acetosyringone, scientists can enhance the efficiency of gene transfer, leading to the production of transgenic plants with desired traits such as disease resistance, improved yield, and enhanced nutritional value.
In addition, it has applications in organic synthesis. It can be used as a building block for the synthesis of more complex organic compounds. Its unique chemical structure allows it to participate in various chemical reactions, making it a valuable reagent in the laboratory for the creation of novel molecules.
When using Acetosyringone in Agrobacterium - mediated plant transformation, first, it needs to be prepared as a stock solution. Usually, it is dissolved in an appropriate solvent such as dimethyl sulfoxide (DMSO) or ethanol. The concentration of the stock solution can vary depending on the specific experimental requirements, but a common concentration is around 100 mM.
During the plant transformation process, the prepared acetosyringone solution is added to the co - cultivation medium at a suitable concentration, typically in the range of 100 - 200 μM. The bacteria and plant tissues are then incubated in this medium for a specific period to allow for efficient gene transfer.
In organic synthesis, the amount of acetosyringone used depends on the stoichiometry of the reaction. It is added to the reaction mixture under appropriate reaction conditions, such as temperature, pressure, and the presence of catalysts. Reaction monitoring techniques such as thin - layer chromatography (TLC) or nuclear magnetic resonance (NMR) can be used to follow the progress of the reaction.
Case Study 1: A research group in a biotechnology company was working on developing transgenic soybean plants with enhanced resistance to a common fungal disease. They used Acetosyringone in the Agrobacterium - mediated transformation process. By adding 150 μM of acetosyringone to the co - cultivation medium, they observed a significant increase in the transformation efficiency compared to the control group without acetosyringone. The transgenic soybean plants showed improved disease resistance in subsequent greenhouse and field trials.
Case Study 2: In a chemical research laboratory, scientists were synthesizing a new class of organic compounds for potential pharmaceutical applications. Acetosyringone was used as a key intermediate. By carefully controlling the reaction conditions and using the appropriate amount of acetosyringone, they were able to synthesize the target compound with a high yield of over 80%. This demonstrated the effectiveness of acetosyringone in organic synthesis.
