💡 Commercial Applications
Pyrazine is a versatile chemical compound with various commercial and industrial applications. It is commonly used as a flavoring agent in the food industry, adding a roasted or nutty taste to products such as coffee, cocoa, and baked goods. Pyrazine is also utilized in the production of pesticides and herbicides due to its ability to act as an insect repellent.
In the pharmaceutical sector, pyrazine plays a significant role in the development of drugs and medications. It is often incorporated into pharmaceutical formulations as an active ingredient due to its biological activity and potential therapeutic effects. Pyrazine derivatives have exhibited antimicrobial, antifungal, and antitumor properties, making them valuable components in the treatment of various health conditions.
Pyrazine’s ability to interact with biological systems has led to its application in the field of medicine. It is used in the synthesis of pharmaceutical compounds targeting specific receptors or enzymes in the body, contributing to the development of new drugs with improved efficacy and reduced side effects. Pyrazine-based medications have shown promising results in clinical trials for conditions such as cancer, infectious diseases, and neurological disorders.
⚗️ Chemical & Physical Properties
Pyrazine is a colorless, oily liquid with a characteristic odor resembling that of roasted peanuts or chocolate. This organic compound is commonly used in the food industry as a flavoring agent due to its aromatic properties.
With a molar mass of 79.10 g/mol and a density of 1.02 g/cm³, Pyrazine is significantly lighter than common household items such as water (molar mass of 18.02 g/mol, density of 1.00 g/cm³) and sugar (molar mass of 342.30 g/mol, density of 1.59 g/cm³). This makes Pyrazine less dense but heavier compared to water, and less dense and lighter compared to sugar.
Pyrazine has a melting point of 41°C and a boiling point of 155°C. These values are relatively lower compared to common household items such as salt (melting point of 801°C, boiling point of 1,465°C) and butter (melting point of 32-35°C, boiling point of 150-175°C). This indicates that Pyrazine has a lower melting and boiling point compared to these household items.
Pyrazine is sparingly soluble in water, with a solubility of less than 1 gram per 100 mL at 25°C. It also exhibits low viscosity, making it easily spreadable and mixable. This contrasts with common household items such as sugar (high solubility in water) and honey (high viscosity), highlighting Pyrazine’s unique solubility and viscosity properties.
🏭 Production & Procurement
Pyrazine, a versatile compound commonly used in the food and fragrance industry, is primarily produced through chemical synthesis in laboratory settings. The production of Pyrazine involves the reaction of certain precursor chemicals under controlled conditions to yield the desired product.
Pyrazine can be procured from chemical suppliers that specialize in providing a variety of chemical compounds to industries worldwide. These suppliers may offer Pyrazine in different forms, such as liquid or powder, depending on the needs of the buyer. Once procured, Pyrazine can be transported in sealed containers to prevent contamination and ensure its stability during transit.
In the transportation of Pyrazine, it is crucial to adhere to strict safety guidelines to prevent any potential hazards associated with handling chemical substances. Proper labeling, packaging, and documentation are essential to ensure compliance with regulations and to guarantee the safe delivery of Pyrazine to its final destination for use in various applications.
⚠️ Safety Considerations
In terms of safety considerations for Pyrazine, it is important to note that this compound is flammable and should be stored in a cool, dry place away from sources of ignition. Additionally, exposure to Pyrazine should be minimized through the use of proper personal protective equipment such as gloves and goggles. In case of accidental ingestion or contact with skin or eyes, medical attention should be sought immediately.
In pharmacology, Pyrazine is a heterocyclic compound that is commonly used in the pharmaceutical industry as a building block for the synthesis of various drugs. It has been found to have sedative, analgesic, and anti-inflammatory properties, making it a valuable component in the development of new medications for a range of conditions. Pyrazine has also been studied for its potential role in treating neurological disorders and cancer, showing promising results in preclinical studies.
The hazard statements for Pyrazine include “H226 – Flammable liquid and vapor” due to its flammable nature, as well as “H302 – Harmful if swallowed” and “H315 – Causes skin irritation” based on its potential to cause harm upon ingestion or contact with skin. It is important to handle Pyrazine with care and to follow safety protocols to prevent accidents and minimize risks associated with its use.
Precautionary statements for Pyrazine include “P210 – Keep away from heat, hot surfaces, sparks, open flames, and other ignition sources” to prevent fires or explosions, as well as “P264 – Wash hands thoroughly after handling” and “P280 – Wear protective gloves/eye protection/face protection” to reduce the risk of exposure and potential adverse effects on health. It is crucial to follow these precautionary measures when working with Pyrazine to ensure the safety of individuals handling the compound.
