2,5-Dimethyl Pyrazine with the CAS number 123-32-0 is a valuable chemical compound. It appears as a clear, colorless to light yellow liquid with a characteristic nutty, roasted odor. The molecular formula of 2,5-Dimethyl Pyrazine is C₆H₈N₂, and its molecular weight is approximately 108.14 g/mol.
It has a boiling point in the range of 156 - 157 °C and a melting point around -13 °C. The density of this compound is about 1.029 g/mL at 25 °C. It is soluble in common organic solvents such as ethanol, ether, and acetone, but has limited solubility in water.
2,5-Dimethyl Pyrazine finds a wide range of applications in various industries. In the food and beverage industry, it is widely used as a flavoring agent. Its nutty and roasted aroma makes it an ideal additive for coffee, chocolate, and baked goods, enhancing the overall flavor profile and providing a more intense and authentic taste experience.
In the fragrance industry, it is used as a key ingredient in creating complex and unique scents. Its warm and inviting aroma can add depth and character to perfumes, colognes, and other fragrance products.
Furthermore, it also has applications in the pharmaceutical and chemical research fields. It can serve as an intermediate in the synthesis of certain drugs and other chemical compounds.
When using 2,5-Dimethyl Pyrazine as a flavoring agent in food and beverage products, it should be added in appropriate amounts according to the specific flavor requirements. Generally, it is recommended to start with a small dosage and gradually adjust based on taste tests. It can be dissolved in a suitable solvent before adding to the product to ensure uniform distribution.
In the fragrance industry, it can be directly incorporated into the fragrance formulation at the appropriate stage of the production process. Due to its relatively strong odor, careful handling and accurate measurement are necessary to achieve the desired scent effect.
In chemical research and synthesis, it should be used in a well - ventilated laboratory environment following strict safety procedures. Appropriate protective equipment such as gloves and goggles should be worn.
Case 1: Coffee Flavoring
A coffee manufacturer was looking to enhance the flavor of its medium - roast coffee. They added a small amount of 2,5 - Dimethyl Pyrazine to the coffee beans during the roasting process. The result was a significant improvement in the coffee's aroma, with a more pronounced nutty and roasted note. Customers reported that the coffee had a richer and more complex flavor, leading to an increase in sales.
Case 2: Perfume Creation
