For R&D scientists and chemical engineers, a thorough grasp of this compound's characteristics, along with reliable sourcing from a competent manufacturer and supplier, is paramount.

Chemical Identity and Properties

2-Acetylbenzimidazole, scientifically named 1-(1H-1,3-Benzimidazol-2-yl)-1-ethanone, is characterized by its molecular formula C9H8N2O and a molecular weight of 160.17 g/mol. It typically appears as a white powder with a purity assay of ≥98.0%, ensuring its suitability for demanding synthetic processes. Its physical properties, such as melting point (around 113-114 °C according to some sources) and solubility (insoluble in water but soluble in organic solvents), are important considerations for handling and reaction design. The compound is stable under recommended storage conditions, typically in a cool, ventilated place, as indicated by manufacturers.

Synthesis Pathways for 2-Acetylbenzimidazole

The production of 2-Acetylbenzimidazole involves specific chemical reactions. While various methods can be employed, a common route involves the oxidation of 2-(α-hydroxyethyl)benzimidazole using oxidizing agents like potassium permanganate (KMnO4). This reaction converts the secondary alcohol group to a ketone, yielding the desired 2-Acetylbenzimidazole. For industrial scale production, manufacturers focus on optimizing these synthesis pathways to ensure high yields, purity, and cost-effectiveness. Understanding these synthetic routes can also provide insights for quality control and impurity profiling, which are crucial for B2B buyers.

Primary Application: Intermediate for Thiabendazole

The most significant application of 2-Acetylbenzimidazole is its role as a precursor in the synthesis of Thiabendazole. Thiabendazole is a broad-spectrum benzimidazole fungicide and anthelmintic, widely used in agriculture to protect crops from various fungal diseases and to treat fruits post-harvest. Its effectiveness makes it a staple in crop protection strategies worldwide. Consequently, the reliable availability of high-purity 2-Acetylbenzimidazole from a trusted manufacturer is essential for agrochemical producers. Companies looking to buy Thiabendazole intermediate or source 2-Acetylbenzimidazole should focus on suppliers that can guarantee both quality and a consistent price.

Potential in Pharmaceutical Synthesis

The benzimidazole core is a fundamental structural element in many pharmacologically active compounds. This inherent versatility means that 2-Acetylbenzimidazole can also serve as a valuable starting material or intermediate in pharmaceutical research and development. Medicinal chemists may utilize it to construct novel drug candidates with potential applications across various therapeutic areas, from anti-inflammatory agents to antivirals. For researchers needing to purchase 2-Acetylbenzimidazole for their studies, sourcing from a reputable chemical supplier is key to ensuring the integrity of their research.
