Overview
2-Acetylpyrrole is a heterocyclic organic compound that features a pyrrole ring substituted with an acetyl group at the 2-position. It is widely recognized for its role in the flavor and fragrance industry, where it imparts a nutty, roasted aroma. The compound is also utilized as a building block in the synthesis of more complex molecules in pharmaceuticals and agrochemicals. The production of 2-acetylpyrrole typically involves the acetylation of pyrrole or through other synthetic routes. Its versatility and unique chemical properties make it a valuable intermediate in various industrial applications.
Physical and Chemical Properties
2-Acetylpyrrole is a pale yellow to brown liquid at room temperature with a characteristic odor. It has a molecular weight of 109.13 g/mol and a density of 1.08 g/cm³. The compound is soluble in common organic solvents such as ethanol and ether but has limited solubility in water. Key chemical properties include its reactivity as a ketone and the aromatic nature of the pyrrole ring. These properties make it suitable for various chemical reactions, including condensation and substitution reactions, which are essential in synthetic chemistry.
Main Applications
In the food industry, 2-acetylpyrrole is used as a flavoring agent due to its nutty and roasted aroma. It is often found in products like coffee, nuts, and baked goods. The compound enhances the sensory profile of these products, making it a popular choice among flavorists. Beyond the food sector, 2-acetylpyrrole serves as an intermediate in the synthesis of pharmaceuticals and agrochemicals. Its structural features allow it to be a precursor in the production of more complex molecules, including drugs and pesticides.
Safety and Storage
Handling 2-acetylpyrrole requires caution as it can be irritating to the skin and eyes. Proper personal protective equipment (PPE), such as gloves and goggles, should be worn when working with this compound. Adequate ventilation is also recommended to avoid inhalation of vapors. Storage should be in a cool, dry place, away from direct sunlight and heat sources. The compound should be kept in tightly sealed containers to prevent moisture absorption and degradation. Compliance with local safety regulations is essential for safe handling and storage.
B2B Procurement Guide
When procuring 2-acetylpyrrole, it is crucial to evaluate suppliers based on their certifications and product quality. Requesting a Certificate of Analysis (COA) ensures that the product meets the required specifications. Buyers should also verify the supplier's compliance with relevant regulatory standards. Price negotiation is common, with rates typically ranging between $50 and $100 per kilogram, depending on purity and order volume. Bulk purchases may attract discounts. Additionally, consider logistical factors such as shipping conditions and lead times to ensure timely delivery.
