Product Name: Factory Supply 2,3-Dimethylpyrazine CAS 5910-89-4 With Best Price
CAS Number: 5910 - 89 - 4
2,3 - Dimethylpyrazine is a heterocyclic organic compound. It appears as a colorless to pale yellow liquid with a characteristic odor. The molecular formula of 2,3 - dimethylpyrazine is C₆H₈N₂, and its molecular weight is approximately 108.14 g/mol. This compound has a boiling point in the range of about 155 - 156 °C and a density of around 1.03 g/cm³ at 25 °C.
1. **Flavor and Fragrance Industry**: 2,3 - Dimethylpyrazine is widely used in the flavor and fragrance industry. It has a nutty, roasted, and cocoa - like aroma, which makes it an important ingredient in creating flavors for food products. It can be used to enhance the flavor of coffee, chocolate, nuts, and baked goods. In the fragrance industry, it can contribute to the development of warm, rich, and gourmand - type scents.
2. **Chemical Synthesis**: It serves as a valuable building block in organic synthesis. It can be used in the preparation of various pharmaceuticals, agrochemicals, and other fine chemicals. For example, it can participate in reactions such as substitution, addition, and condensation reactions to form more complex organic compounds.
1. **Flavor Application**: When using 2,3 - dimethylpyrazine in the flavor industry, it should be diluted properly. Usually, it is first dissolved in a suitable solvent such as ethanol or propylene glycol. The concentration of the solution depends on the specific application and the desired flavor intensity. For example, in coffee flavoring, a typical concentration might range from 0.1% to 1%. It should be added at the appropriate stage of the food production process, usually during the mixing or flavor - blending step. Care should be taken to ensure uniform distribution of the flavor in the product.
2. **Chemical Synthesis**: In chemical synthesis, the reaction conditions need to be carefully controlled. The reaction temperature, pressure, and reaction time should be optimized according to the specific reaction. It is often used as a reactant in the presence of appropriate catalysts and solvents. Safety precautions such as wearing appropriate protective equipment (gloves, goggles, etc.) should be followed during handling.
1. **Coffee Flavoring Case**: A coffee flavoring company wanted to enhance the roasted and nutty notes of their coffee flavor. They added 2,3 - dimethylpyrazine at a concentration of 0.3% to their existing flavor formulation. After rigorous sensory evaluations, they found that the new flavor had a more intense and authentic roasted coffee taste. Consumers also preferred the new - flavored coffee, which led to an increase in sales of their coffee products. The company was able to meet the growing market demand for high - quality coffee flavors with the help of 2,3 - dimethylpyrazine.
2. **Pharmaceutical Synthesis Case**: A pharmaceutical research group was synthesizing a new drug compound. They used 2,3 - dimethylpyrazine as a key intermediate. By carefully controlling the reaction conditions and using appropriate catalysts, they were able to successfully synthesize the target compound in a high yield. The use of 2,3 - dimethylpyrazine in this synthesis not only simplified the reaction steps but also improved the overall efficiency of the synthesis process, bringing the new drug one step closer to the market.
