For professionals in the chemical industry, a deep understanding of key organic compounds is crucial for both research and procurement. 2-Methylbutyric Acid, identified by its CAS number 116-53-0, is a significant branched-chain carboxylic acid with diverse industrial applications. From its characteristic aroma that enhances flavors and fragrances to its utility as a synthetic intermediate in pharmaceuticals and agrochemicals, this compound is of considerable interest. This article provides a comprehensive overview of its chemistry, synthesis, and market, guiding you on how to effectively buy this essential chemical.

Chemical Profile of 2-Methylbutyric Acid

2-Methylbutyric Acid is a five-carbon carboxylic acid with the molecular formula C5H10O2. It exists as a clear, colorless to pale yellow liquid. Its physical state and chemical structure contribute to its reactivity and sensory properties. The molecule features a chiral center at the second carbon atom, leading to R and S enantiomers, though it is commonly supplied as a racemic mixture. Its odor profile is notable: pleasant and fruity at low concentrations, becoming pungent and cheesy at higher levels. This dual sensory characteristic makes it valuable in flavor and fragrance formulations. Its solubility in water and organic solvents further adds to its versatility in various chemical processes. Understanding these basic chemical properties is fundamental for anyone looking to buy this compound.

Synthesis and Industrial Production

The industrial production of 2-Methylbutyric Acid can be achieved through several synthetic routes. Common methods include the oxidation of fermentation amyl alcohol (fusel oil) or the decarboxylation of methyl ethyl malonic acid. Advances in chemical synthesis also allow for enantioselective preparation if specific isomers are required, though the racemic form is more common for general industrial use. Manufacturers capable of producing this compound with high purity (e.g., ≥ 97.5% by GC) are preferred, especially for demanding applications. The production capacity, often cited in tons per month (e.g., 200 tons/month), indicates the scale at which manufacturers can meet market demand.

Market Dynamics and Procurement Tips

The market for 2-Methylbutyric Acid is driven by demand from the flavor and fragrance, pharmaceutical, and agrochemical sectors. When planning to buy, it is essential to consider market price fluctuations and to procure from reliable sources. Identifying manufacturers who offer competitive pricing, consistent quality, and stable supply is paramount. Companies often look for suppliers with demonstrated export experience and positive customer reviews. Requesting quotes from multiple manufacturers in regions like China, which hosts numerous chemical producers, can yield significant cost savings. Always seek detailed Certificates of Analysis (COA) to confirm purity and specifications before making a purchase.

Conclusion

2-Methylbutyric Acid (CAS 116-53-0) is a compound of significant industrial value, bridging the gap between sensory applications and complex chemical synthesis. By understanding its chemistry, synthesis, and market dynamics, and by diligently selecting suppliers, businesses can ensure they source this essential organic chemical effectively and economically, thereby supporting their product development and manufacturing goals.
